Today’s post is focused squarely on supply side Milenomics.  I won’t get into how many miles you should be collecting, but I will caution you, you should be keeping an eye on your totals and stay away from hoarding miles. Switch to cash back cards when you’re at a safe supply level is an excellent way to balance cash back and miles.  Whether you’re earning miles or money, the following advice is true either way.

Scaling Works Great, Until it Doesn’t.

1 plantI’ll start with a small example, and one totally unrelated to Miles and points.  I’ve just planted my garden at home, and living in the city I have limited space.  I know that I can plant one tomato plant and harvest 200 tomatoes from that plant.

If I think that I need more than 200 tomatoes I can just plant another tomato plant.  I’ve gone from one plant, 200 tomatoes to 2 plants, 400 tomatoes. This is a very rough, very academic, simplistic form of scaling production.

For my garden my inputs are land, water, fertilizer and my time.  My total land for planting might only allow me 10 tomato plants, so this is a hard limit I need to keep in mind..

many plants

But even with unlimited amounts of land and water I can’t scale to infinity because of my time. Even if I had unlimited land at some point I’d have to quit my job and become a farmer full time.  And even then with only 24 hours in a day, I’m still looking at a hard limit there as well.

So if I’m in the business of selling tomatoes (I’m not) and I see that my Tomato crop is booming, I need to always keep an eye out for where my scaling falls apart due to limits.

Similarly, while I’m working to produce Miles I want to keep an eye on where my scaling starts to break down.  Next, we’ll discuss a few of the roadblocks to scalablity.

Roadblock #1: Daily/Monthly Purchase Limits.

We’re all familiar with these types of limits. The most famous of these is the CVS $5k per day limit. Daily purchase maximums such as these, and your monthly Credit Card Limit are a few examples of this.

Example: My local Rite-Aid will limit me to 2 cards on credit per trip. I know this is a store imposed limit–but it is still one I need to keep in mind whenever I plan a trip there.

Keep these limits in mind and plan trips around them. Group your purchases to Save on time and Travel, and increase the amount you can spend beyond any one store’s Daily purchase limits.

Roadblock #2: Time

Today I’m asking you to also consider your time in this scalability. The first step in doing so is to ask yourself how much time you can reliably give to this effort.  If it is 1 hour a day or 9 hours a day, know this amount and stick to it. Your Maximum Daily Hours should take into consideration your goals, but also your current situation in life, and your Supply and Demand for miles. Someone who’s trying to churn enough money to pay their tuition  might decide to dedicate 5+ hours a day to this. Someone else with a family and plenty of other hats to wear might decide they only have an hour to do so.

Consider the following examples:

A. 1 hour work x $10k spend (and liquidation) at 2% = $200 
B. 2 hours work x $20k spend (and liquidation) at 2% = $400 
C. 1 hour work x $10k spend and liquidation at 4% = $400

In the above we’ll often forget this extra hour of our time in comparing option B and option C.  It is easy to think you’re netting the same amount when you look at what you’re taking in–Never forget your time in your calculations. The true calculations for the above should be:

A. 1 hour work x $10k spend (and liquidation) at 2% = $200 ($200/hr)
B. 2 hours work x $20k spend (and liquidation) at 2% = $400 ($200/hr)
C. 1 hour work x $10k spend and liquidation at 4% = $400 ($400/hr) + 1 extra hour of time at your T-rate.  For me that would be $425.

Scale your time last. Working 2x harder is great, but working just as hard and netting the same amount as if you worked 2x as hard gives you 50% more of your time:

Roadblock #3 Liquidation Limits

Even if we’re able to scale to infinity on the purchase side we’ve got to be conscious of our limitations with respect to liquidation as well.

Something like the hard limit on the number of swipes you can do at Wal-Mart is a good example of this. There might be ways around this limit, but those ways include wasting 10-15 minutes of your time.  And while cashiers should in theory allow you unlimited swipes, at some point you’ll draw attention to what you’re doing and be shut down entirely.

As your total number of cards to liquidate increases your ability to liquidate them actually decreases.

It is for this reason that you’ll want to seriously consider passing up $100 and possibly even $200 gift card purchases.  With the right multiples that might not be true–but consider the scalablity of your liquidation when you purchase any item. $2500 is cheap and easy to liquidate when you’re talking about $500 cards, and nearly impossible to do in one day if you’re talking about $50 cards. It isn’t the total, its the quantity. 

Example: Evolve Money was a great service which has in the past scaled very high. A theoretical limit for the service might have been $30k in payments per month ($1k per day x 30 days). However with the current 4 payment limit per month you’re now limited to no more than $4k per month per account.  What that means is that you’ll also need to adjust your purchases due to this change.  Whereas Evolve was a great way to dump $100 and $200 cards in the past I’m now using it almost 100% to get rid of $950 Reload-it packs, since I want to maximize the value I get from the service.

Scalabilty is also loosely related to the float rule. You should consider what you’ll need to hold onto without being able to liquidate due to issues of scale.  Had I bought $12,000 in $100 Gift cards instead of VR thinking I could liquidate them Via Evolve I’d need two and a half years to liquidate them all at the current 4x$100 per month maximum.

Be ready for any liquidation method to die tomorrow.

Economies of Scale in Mile Production

All of this leads us to look at our own personal economies of scale in the production of miles. An example of this is the recent Safeway $20 off when you buy $200 Visa gift cards deal we discussed last week here on the blog. The cost for miles with this deal is negative–spend $6.95 to get $20 off of groceries. However this negtive cost is only true in the short run.

Economies of Scale
Every production line you have has its own LRAC curve. Above is a hypothetical curve for the $200 Safeway deal we discussed here on the blog last week.

We’ll get into the reasons why this is true by stepping through this above chart. Imagine this chart is a visual representation of your costs to produce, and your output of miles you’ve earned through the Safeway deal.  We’ll discuss the different points on the chart as follows for the $200 Safeway deal:

Q: As you start purchasing your costs are your time, and your travel, along with $6.95 in fixed costs.  For each purchase you make let’s assume you earn 2 $10 off coupons, which work to drive your costs lower and lower. At point Q you’re buying 1 $200 card, and “earning” $13 in free groceries, for a total cost of -$13 (plus your time and travel).

Moving from Q to Q2: As you move along the LRAC curve between these points you start to see benefits from economies of scale. Maybe you’re able to buy 2-3 $200 cards per trip, cutting your costs down. In addition you’re able to consolidate your coupons and use them all in one trip, further reducing your costs for the deal. You can then unload them at home nearly instantly with AP or EvolveMoney.

Q2: At point Q2 your time and travel have been averaged out by your coupon purchases, and you’re earning miles and money along the way.  At this point your cost to manufacture (C1) are at their lowest point. You’re running at peak efficiency. This operation is so great, it should be able to continue driving costs down forever, right?

No. As you can see your LRAC (Long Run Average Cost) starts to creep up slowly. You’re now into Diseconomies of scale  The reasons for this increase in your cost could be as simple as:

1. You now have more coupons that you could ever hope to use. Having no use for your coupons, you now can’t get any value from them at all.

2. Or you scramble to use them and purchase things you don’t really need, and at prices which aren’t competitive, wasting money along the way an negating the coupons’ actual cost savings.

3. On the liquidation side you’ll see increasing costs as your ability to liquidate quickly from home goes away and time, travel, and fees start to add to your total costs.

Whatever the reasons your costs will creep up once you’ve passed maximum efficiency.  That isn’t to say you shouldn’t continue purchasing past Q2, just that you should seriously consider when to stop going in on a deal.

 I often stop my purchases of gas point earning cards once I feel I have more gas points than I can safely get rid of.  Otherwise the costs to acquire will continue to creep up as unused gas points no longer help offset purchase fees.

Having an operation with many different production lines running all at peak efficiency should be our ultimate goal. Maximum efficiency also frees up your time to take part in another deal, and increase your total miles earned.  Remember, as we discussed above we should be working smarter, not harder. And we should respect our maximum daily hours whenever possible.

Hidden ways to Scale Production

When you’re faced with no longer being able to scale a deal you have a few options. Before you consider stopping that production line you should try the following to increase the miles you’re producing and/or lower your cost to do so:

Increase the multiplier on your credit card. In this way you’re continuing to scale up beyond your normal capacity. Going from a 1x to a 2x card or from a 2x to a 3x card means you can continue to see economies of scale beyond your current limits.

Double or Triple Dip. Can you earn cash equivalents like coupons, gas rewards, or rebates through purchases? If so keep an eye on your logical limits to scaling these rebates/coupons.

Lean out your Liquidation costs. There’s no sense in traveling farther than you need to if all you’re doing for liquidation is buying $500 Money Orders. Look for Gas, Drug, or Groceries closer to home that will sell you these same items on debit. Use the time you save to scale up production.

Scale past your own limits: In the above Safeway example we discussed being unable to continue to use an infinite number of coupons.  The same holds true for Gas rewards–you can only use so much gas.  Look for ways beyond those limits. Do you have a neighbor who’s buying diapers all the time? or someone you know who could use gas rewards for their fleet of vehicles? If so, work out a deal where you sell them your coupons or gas rewards for a discount.  I’ve successfully sold gas rewards to a local delivery business at 50% of face value.  This means I can increase my production of those cards which earn gas rewards and shift my entire LRAC curve further to the right (LRAC2):

Shifted Curve
Hypothetical Curve for Gas reward earning card purchases. In this new, shifted LRAC curve you can see that at any given cost your output is now higher. Trough an additional multiplier, leaner liquidating costs, or smarter ways of acquiring you’ve increased your ability to earn miles at a given cost.

Wrap Up:

Full production at maximum efficiency is a beautiful thing for all of us to strive for. Today’s discussion of scaling doesn’t change the basics of what to do once you have those miles:

1. Know your Total Costs. Keep track of these costs with a tracking sheet that shows your average cost per mile. Include your time and travel as these are very real costs, and are often times limiting factors.

2. Use your miles whenever the cash price of a ticket is equal to or greater than your cost to manufacture your miles. In this way you realize your investment of your time.

Knowing the total cost to manufacture miles will let you stop activities which are not a great use of your time.

6 thoughts on “Scalablity — You Either Have It or You Don’t

  1. Excellent post. I don’t personally use a T-Rate, but I do look very hard at rewards earned per minute spent. T-Rate just establishes a minimum for rewards earned per minute spent.

  2. Yup, great post indeed.

    I have stopped buying the GCs that came with the two $10 coupons for just the reasons you mention. Finally liquidated one today and now have just one more to go. I did have some success getting some cashiers to allow me to use them without spending the full $25 – I showed them the original ad that did not say there was a minimum spend – but that’s been hit or miss and today’s cashier wanted the full $25. It was easy when I only needed to spend $10. $25 is harder and more time consuming.

    While we need to know these principles so when an offer comes along we can decide if and how much to scale, what I really need to do is scale what should be regular, monthly MS. Right now it is pretty haphazard and what I should devise is a monthly plan that says for example:

    Day 1 – move $$ from Bank Acct A (where paycheck is deposited) to Suntrust Acct B and/or UFB Direct
    Day 2, 3, or 4 – buy MO using Suntrust, pay Citi using UFB, and
    deposit MO into Bank Acct C or D or E
    Day 5, 6 or 7 – Use CC to do Amazon Payment on AP Acct 1
    etc.

    Right now I let the GCs and prepaids I am able to pick up, and the minimum spends I am working on, drive the schedule, so it is quite haphazard and buying MOs using the denit cards can get lost in the shuffle. As a result I am doing less than I might do if I had a monthly calendar driving at least some of it, especially for the ST and UFB debit cards and AP.

    Partly this is deliberate: the result of not wanting to do things on a very regular schedule. I like to vary amounts and dates of activity. But some general plan would probably lower my t-rate substantially while increasing my total MSing.

  3. You made a comment about unloading $950 Reload packs using Evolve – can that be done directly or do I need to reload onto a prepaid debit card first? The reason I’m asking is Paypower is already holding my funds due to “risk” and I’m afraid the same thing will happen soon if I keep on reloading so much onto the Tmobile card. Is there anyway to minimize that risk? Thanks!

    • Will: You can do it directly. When you go to pay select “Cash” and then Reload-it. You’ll enter the pack number and amount and then the payment processes just like any other.

  4. Great article. I’ve been thinking about the time factor for quite a while now. For me, its makes more sense to pursue as much negative cost MS on my butt as possible. That means buying AGC through portals and then cashing out at GCM. Use the “profits” to offset card fees on SMGC online orders instead of going in person where the savings is only about half a percent but the time is quite intensive.

    Suddenly AFT makes sense due to their convenience, but I the registers seem to be hard coded to not recognize them (I have four in hand that I imported).

    I haven’t figured a way to move beyond $35K per month in a way that requires little time.

    Acquisition is easy. Quick liquidation for amounts beyond 35k is the where I’m stuck.

  5. Scalability
    A simpler way of looking at this is to add family or just double a deal with a spouse

    A single 100k AA exec card app gets 100k miles + 10 k for spend at a cost –
    450$ fee – less 200$ rebate + 200$ opportunity cost of 10k spend
    So 450$ for 110k miles = 0.4 cpm
    Jump on it with your wife and siblings = total 5 =
    now you are looking at 550k miles for 2250$
    That is serious multiplication without too much of an increase in your valuable time
