I wish you all would say what brand of strips you are talking about, whether good or bad.
Only once have I had a box of expired strips. They were One Touch strips backin the days when One Touch took a "long time" (What was that? One minute? Forty seconds?) to give a result. The results seemed to be reliable, though they were 1 year past the date.
If someone wanted to give me an expired box, I would cheerfully accept.
