My wife spotted this one.

A local grocery chain has 4 12 packs of Coke products on sale for $10.00.

There is a rebate from Coca-Cola for $10. You need the rebate form, 4 proof-of-purchase from the 12 packs. Not a bad deal, unless you are bad with rebates. It is a bit of a hassel since you must cut up all the boxes, ok if you plan to drink it all right away. Just one per household.
I was smart this time, my wife is in charge of sending in the rebate. 🙂
