I look at it this way-
Upfront expenses:
Alpha track meter- $100+ to buy
strips- I think they are $1 EACH
vs
Relion Micro- $15 (they just went up- I bought mine in January for $9- honest!)
strips- store- 100/$36 ($.36 EACH) and ADW 250/$72 ($.29 EACH)
I test, on average, 7 times a day.
Alpha- 7*1.00=7.00/day, 49.00/wk, 196.00/4 wk month.
Relion- 7*.29= 2.03/day, 14.21/wk, 56.84/4 wk month.
I save $139 a month by using a human meter, on average. Sure, every 45 days my auto-ship order comes from ADW ($73 because of the auto ship discount covers most of the shipping cost) but I've built that into my budget.
But lets say you only test 3 times a day because of time constraints (both PS shots and one mid-cycle)-
Alpha- 3*1.00=3.00/day, 21.00/wk, 84.00/4 wk month.
Relion- 3*.29= .87/day, 6.09/wk, 24.36/4 wk month.
Comes to a $56 savings. That's a lot of cat food (or people food, utility bill, car payment...)
Plus, consider this- Walmart is easier to get to in the middle of the night (for at least half of us)- your vet isn't open at midnight if you need extra strips NOW!!! I've had many a teller say they can open those plastic little boxes for me if the pharmacy is closed.
Most people get what they can afford. I can afford Relion Micro strips- they are consistent, reliable, and they don't take a lot of blood.
