First, there other companies out there that buy test strips and have larger payouts than cashfordisabetics.com such as https://teststripbuyers.com (wish I saw that first). Second, be careful and read everything they send you, not just the legalities of the terms and conditions. Let me be clear, it was my fault, I didn't look close enough and ended up getting $10 for boxes they were supposedly giving $20 a box for. I only read through the terms and conditions, which is what I believe you are legally agreeing to. Their terms and conditions did not state anything about expiration dates. Of the 20 boxes I sent them, 16 had expiration dates that fell within a 9 month range which reduced the payout in half. I truly believe that their terms and conditions are not specific enough and need to be changed. If you choose to use them, just be careful, they get to decide what your payout will be and could be significantly less than what you are expecting.
