This is just a heads up that Walmart has updated their registers in their newest coupon update. This is good and bad. The good is that it is going to (in the long run) help prevent coupon fraud- which is a huge problem. Unfortunately, not all the employees have been properly trained and since this is brand new, not even the managers are quite aware of what to do when a coupon beeps. For now be warned you maybe in checkout a little longer then normal. I have found if your coupon beeps they will call the manager and then the manager will make sure it matches the coupon and process it through. Also beware not all employees will be nice and will flat out deny it even when you buy the right product.
As always, keep a copy of the Walmart Coupon Policy in your coupon binder and have on hand in case of a question when you shop.
