I want to add that when i had a 'dealings" with coupons i called corporate and even went as far as the district manager and their response was:

"Walmart has the right to change their policies as needed to suit their customers needs"

Now i know in my case there is an employee that is allowed to use coupons i was refused to use! Oh well i shop at other walmarts where they want my coupons and if there are any more dealing with any other walmart, i will shop at a totally different store
