Android app brings coupons & buyer cards to your phone

I found this Android app that I simply LOVE (for those who use iPhone, they should have a version as well). It is called "The Coupons app". You can pull up coupons for stores and have them scanned right at the register. If you prefer to print them, you can send it to you email for printing.
Another app I found helpful is call "Key Ring". It allows you to input all of your frequent buyer card info into it so that you don't have to carry all those little plastic tags around on your keys. I can't tell you how many times I left the house with a friend and didn't have my buyer cards with me. Now all I have to do is remember to bring my phone for the extra savings!
