Well, I have the Walmart Store coupon Policy, that you can see HERE. But not much else for Walmart, they have no store coupons, no rewards cards, just “everyday” low prices! I will say that at Walmart you can get items for free with coupons, and sometimes “overage” using coupons [coupons that are more than the product, will SOMETIMES allow for the difference to come off your total]. I wouldn’t get mad if the cashier won’t allow it, because I don’t know if its “allowed” or not. Sometimes I wish there was a “universal coupon policy book” , so everything would be easier!
