For insulin, Walmart sells 70/30 insulin for only $24.88 a bottle. They have a special deal with Novolin, that regular pharmacies can't get, so regular pharmacies have to charge over $100 a bottle. So get your 70/30 there.
For test materials: The True Metrix blood sugar meter and strips are the cheapest available that are also reliable. 100 strips on Amazon are less than $18, and the meter on Amazon is $40 with free shipping and includes 100 test strips, 100 lancets, and a lancing device: https://www.amazon.com/TrueMetrix-Blood-…/…/ref=sr_1_4_a_it…
For insulin syringes, you have to have a prescription, but you can order them online at, of all places, pet supply places. Here's the one I used to use: http://www.allegromedical.com/…/monoject-insulin-syringe-1c…
For the three month A1C test, you can go to Dr Griffin, and he'll do it for $50, or you can order two tests, which will take care of six months of testing from Amazon, https://www.amazon.com/A1C-NOW-test-kit-…/…/ref=sr_1_9_a_it… and that runs about $44 with free shipping.
I'm a diabetic who was without insurance for years, and this is how I stayed alive. I have no hidden agenda, just want to help people in the same boat I was in.
