Gosh I love Walmarts Coupon Policy

Man, I know Walmart is evil and all but man they have awesome coupon policy.  It's the only store that I know of that offers COUPON overage.  What that means is if your product is $1 and your coupon is $2, they'll credit you the $1 difference into your receipt which means free money to apply to your total purchase!

Like as in example its been reported on hip2save that Walmart has travel size version of Listerine Total Zero Mouthwash for $1.72.  This coupon above which is pretty high value for Listerine, a good one to print and keep at Walmart would give your $.28 in overage.  So if you have staples like bread, fruit and veggies that don't really have coupons this would help reduce the cost of those items.

And keep in mind, you can print two of these from one computer so that's like 2 free items, and $.56 in overage to apply to lets say a banana or something you need but wouldn't be able to get on the cheap.**  I would print this from Swagbucks to get 10 Swagbucks per coupon redemption to top it off.
