Staples (a U.S. chain of office supply stores) has the easiest rebates of any store I deal with. Some can be done easily online, but some are automatic- give your rewards card number at the checkout, and the rebate check is automatically mailed to you. They sometimes have products with 100% rebate. For example, today I bought a $14 plastic storage box, I didn't have to fill anything out, they'll automatically mail me a rebate check for the full amount in a few weeks. Next week they'll have $15 packs of photo paper on the same deal (limit two per person). Seems like a good way to get free stuff and rack up a small amount of credit card miles at the same time. (I will need to check and see if the sales tax is also rebated). These aren't in the class with mint gold dollar coins, but it's still a nice little thing.
