Most of the time you can't use two coupons on the same item. But you often can use a "store" coupon and a "manufacturer's" coupon on the same product. It pays to ask. For example, I recently used a Walgreen's store coupon to get jars of almonds regularly priced at $3.49 each for $1.75 a piece. Then I used a 75-cents-off-two-jars manufacturer's coupon, driving down the cost of each jar of almonds to $1.37 a piece — a savings of nearly 61 percent off the regular price. Sometimes, using a store coupon and a manufacturer's coupon will get you the item for free.
