I believe I read a post on here yesterday that stated Walmart would not accept online coupons. I went to Walmart last night and they would not accept coupons I had printed. The cashier stated that they had to have "the barcode" at the top right. So needless to say I was really ticked off because I could not use the coupons! I don't know why it would make any difference as long as the "bar code" was on the coupon!
