Oh God. Is that the new black market item? Diabetes has touched my life in several ways, and this makes me a bit sick.
You can tell exactly what's going on here. If you're on Medicare and Social Security with the Part D prescription coverage you can get test strips at a reduced rate. If you're trying to live on Social Security any addition money is a blessing. So you sell half your test strips for extra cash and only test your blood glucose half as much as you should, even though testing is necessary to determine if your medication is working correctly and to make sure you are not getting into trouble health-wise. But you've got the money to buy groceries.
Or you're one of the working poor who make a little too much to get Medicaid or assistance. Test strips are expensive, some of them around $1.00 a strip depending on the brand, and depending on your condition and your medication you may have to test your blood glucose three or four times a day. So you buy test strips more cheaply on the black market, where they may be expired or have been kept in extreme heat or cold, which affects their accuracy. You don't know if the results from those strips are correct or not. You may be calibrating your insulin injections using a bad number. But you can't afford to go down to the Rite Aid and buy them for full retail. Not and pay the light bill too.
I can't drive by this sign every day and not almost cry.
