A few things:
I am using an InRatio machine, and I read somewhere that the strips are still good for one year after the expiration date. I have some that expired late last year, haven't been refrigerated, and haven't generated any quality control errors.
I have gotten strips from vendors on eBay, with no problems, and didn't have to wait for insurance company approval or the other nonsense. (I'm not insured, so although I don't have to fight for reimbursement, the strips come out of a very slim pocket). The strips I bought on eBay didn't require a prescription, either. It may be worth considering an alternative source -- the strips all come with quality control built into them so you probably won't have to worry about test inaccuracy, you won't need a prescription, you won't have to wait for approval -- but you probably will NOT get reimbursement. Alternatively, there are probably some medical supply companies that will sell to your doctor at a 'fair' price (not what some greedy companies call 'convenience') and perhaps a friendly doctor will order them for you from one of these companies - and you can reimburse the doctor.
Of course, this is just what I've done from personal experience and I can't suggest that you do anything other than purchase from site approved vendors.
