Overage

Overage.  I love overage.  Some stores allow it.  Some stores do not.  Some stores don't really allow it but haven't programmed their registers to prevent it.

Overage works like this:

I have a coupon for $5 off any size Pantene Shampoo.  My local store has Pantene Shampoo at regular price for $4.  There is not a size restriction on the coupon, so I give the item and my coupon to the cashier.  If the coupon goes through, then I have just received $1 overage. 

The key to overage is to use it to lower the cost of other items you are buying.  I have yet to find a store that will actually hand you back the overage in change!  So, always do your math and make sure that your total after coupons will still be over $0 when you are done redeeming coupons.
