Test Strips - How long are they good?

Ok, so a while back I got a monitor and intermittently check my glucose levels. Finally I noticed my test strips expired 08 / 2016 ... no wonder I get funny numbers!

Anyway, my question is this -- how long are these things usually good for? I mean, I can go to the pharmacy and look at the expiration date, but maybe it's already been sitting on the shelf for months and I could get longer lasting ones from a pharmacy that sells more of them, right? I just don't know how long they might be good for.

If they're only good for a year, I don't want to buy 50, esp. if they've already been on the shelf for 6 months. See what I mean?

Incidentally, these are the CVS brand strips for the CVS glucose monitor.

Thanks for any opinions.

Oh, they have an expiration date, I just didn't know how far out an expiration date one normally expects to find. So yours seem to have had a date about a year out from purchase. So you probably wouldn't buy any where the date is 3 months from purchase, as that would mean they'd been sitting on a shelf for 9 months. (See what I mean?)

So when I go shopping I'll look for an expiration date about a year out. Thanks.

Found some that don't expire till March 31, 2021 !! Thanks, y'all !

Yes, the CVS brand. I checked every box on the shelf and purchased the ones with the furthest out date. No way will I use all 50 of them between now and then, so if anyone wants about 30 of them.....just ask! lol
