I got sick and tired of having a dozen little “bonus” cards to carry around, so I made this simple fix. Basically, I just scanned in all my barcodes, fit them nicely into a row in photoshop and then printed them out onto a card.
Someone has come up with an online service. Simply, go to http://www.justoneclubcard.com/ and enter in the barcode numbers for 8 of your club cards. The service generates a card, front & back, with the barcodes for those 8 cards. It’s free and you can create as many as you would like. If you cannot find a store listed, just e-mail him photocopies of your card & he will add it to the service.
