I am obsessed. We have a friend who works at penny's who got us our first ones (maybe five?) and each time I redeem them I get more. I have gotten 25 bucks to spend so far-- ended up redeeming them for K cups. I have six more buttons....hoping I get more because I want to get more! They are so expensive but we go through them like crazy and with the button certificates you can get them really cheap! Definitely worth the trouble of redeeming the buttons, lol!
