Grocery coupons can save you money, but only if you use them for things you would buy anyway. Most stores have membership cards that give you electronic discounts on their specials at the checkout. Their fliers or websites can tell you the specials for the week. You also can find product coupons online as well as in newspapers and store fliers. If you find a good deal, and the store has run out of that item, ask for a rain check at the customer service counter. But even with coupons, compare prices. Sometimes other brands or store brands are still cheaper! Coupons can be great, but are not always the best buy!
