If you are trying to keep track of how much you are saving your family with shopping sales and using coupons, you need to look at your receipt closely. Most grocery stores will have a "Savings Summary" that will nicely total your amounts saved for vendor coupons, store coupons, sales, etc. What this summary probably won't take into consideration is any rain checks. When you use rain checks, they often manually enter the price of the item according to the rain check. If this happens, the computer does not see this as a savings of any kind. When you cash in your rain checks, make sure to add the difference in the regular price and rain check price to your total savings. Otherwise your savings is not truly correct and your numbers will show less saving then you actually had. You know we don't want that, now do we?!
