It seems more and more stores have their own rewards cards now. I used to keep them on my keychain, but now there is an easier way--store them all in your phone with the free app CardStar. The app simply stores a picture of each one (which you can take with the phone, or upload from your computer) and get rid of the hard copy. The barcodes can be scanned right at the store from your phone. Having your phone with you anyway makes this an easier solution to keep yourself organized and prepared.
