The club card is a great idea, allowing you to trade marketing data for deals at many stores. The only problem with them is that you have to carry around a few more cards in addition to any credit and bank cards you already carry. The solution is simple: Just One Club Card. This site lets you type in the barcode number form you various cards, and then print out a single card with up to eight club card barcodes on it. The next time you go to use a club card, just find the right barcode, scan it, and youâ€™re on your way. Brilliant!
