Rainchecks!

So you've found a great advertised item and matched it to your coupon, drove to the store to find out that all the items have been sold!  No worries, just ask for a Raincheck!   The store will give you a raincheck for the sale price of the item.  When the sale is over and the items are stocked, you can go back to the store and they will honor the price on the raincheck, combine this with your coupon and you'll get a great deal!
