Just curious if anyone else has had troubles stacking at Walnut Grove Save On? Last week I bought wonder bread and nature's bounty with no problems. The next day I used the exact same stacks and the cashier (who was really snooty but that's another story) gave me the coupons back and said I could only use one because they were all from the same source... any one else encounter this? All the UPC were different. :shrug:
