Save Fast Food Receipts

Normally when we occasionally stop by a fast food restaurant we used to discard or leave behind our receipts but now I keep mine in my car. If I end up stopping by some other day, I will first check the receipts and see if they offer a buy one get one item (often a sandwich!) at the bottom of the receipt for sharing about my visit online. I will THEN go online and answer their questions then get the code to use that receipt for a BOGO immediately afterward!

Some (McDonalds) are only valid for 30 days, but others (Burger King for instance) have no expiration on them. Usually fast food stops aren't planned so this is a great way to save money with very little effort!
