Query: Check the expiration date!!!!

I had a 3 year supply of these strips and after a while I was getting readings all over the place until I realized they have an expiration date. Im the type who keeps milk in the fridg until it turns into a block of cheese. the first thing I did when I got my new supply was check the epiration date. it seems that an expiration date that is one year from the date of purchase is acceptable. the 102 count gives me enough fresh strips for 3 months,they are accurate and the price is very reasonable. Best of all I can be sure the date is still within this decade. This is a good buy
