If you get tired of carrying all of your grocery and other discount cards in your wallet or keychain, there is a website called justoneclubcard.com where you can generate one card which lists all of your discount card information. It's really convenient, neat and costs nothing. I heard about it on my local radio station. All of the correct barcodes are printed after you enter each store. Not all stores are available which the author lists on his website. However, there are plenty of stores that he has already programmed into this applicaiton.
