With your eyes open, I’d like for you to take a small journey with me. The economy is tanking and you have a family of six to feed. Food prices have reached an all time high and you need to find ways to cut costs. In a valiant effort, you buy a Sunday newspaper and browse through the pages of coupons. You see some things that you buy on a regular basis and realize those thirty-five cents here and a dollar, fifty there could actually help lower the bottom line of your grocery bill. You take your pile of coupons to the grocery store and at the checkout stand and your eyes light up when you scan your coupon’s barcode across the scanner. The bar code on that coupon has information imbedded into it that tells the scanner how much to take off your purchase.
