On Friday, Meijer is printing $5 off your next order for each gift card over $50 purchased (one per transaction, no limit). On top of that, with their mPerks reward program, you can earn $5 off a future purchase as well, and can do that up to 10x.

A couple details. Only 1 of the printed off coupons can be used in a future transaction at a time, but the mPerks rewards can be stacked after earning multiple $5 off on a future purchase.

They have just about every retailer I can think of, and then some. They also have eBay cards.
