Use "Double Coupon Checker" to quickly check whether the coupons you have can be doubled. Simply scan your coupons from Sunday newspaper, "Catalina" print-out, or grocery store on your iPhone, iPad, or iPod Touch (auto-focus capable device required). All coupon barcode formats (Databar, UPC, and UPC+Code128) are supported. Note: What is printed on the coupon may NOT match what is encoded in the coupon barcode. If there are any discrepancy, the writing on the physical coupon prevails. Suggestions, comments, problems? Contact [email protected]. We can't help you if you don't contact us.
