Wal Mart and Target seem to be battling over who can provide us with the best deals. They have similar store types with similar merchandise, both offer price matches from each others ads, but Wal Mart has done something that I could only dream of!
According to their official new coupon policy here, "Coupons may exceed the price of the item. Change may be given or applied toward the cost of the basket purchase."
Really?! I hope this lasts, because this is awesome. Now getting the cashiers to do this will be the real challenge. You might want to stay away for a while until people go and report their success/failure. Or you can print the policy to have it handy.
