Glucose meters

Hi everyone! I have a question. I just got another new meter. I have been trying to find something to do with my old one.s I hate throwing them away! Can someone help me?

save it! Just in case the the strips go on sale. I have all sorts of meters. i love the one touch, but they’re to expensive to buy. My new fave meter is the keynote, i got the new micro relion brand meter to try to.
