Today I used several monopoly tickets that had either free or cents off prizes. The clerk scanned the bar codes on the tickets at the end of the check out. He didn't mention that he charged me for two items that were suppose to be free. I didn't catch it right away and had to take my receipt back and got a refund. Why doesn't you register throw up a red flag that indicates the customer did not purchase the free item? One item was Crest toothpaste. The manager said the "Scope" might not have been covered by the free ticket although I think it was the same price and size as other varieties of Crest. The ticket only says the size and "assorted varieties" The other item was Signature frozen vegetables. I couldn't find the 12 oz size indicated on the ticket so I bought a 14 oz size thinking the clerk would let me know the free ticket did not match the item I bought. The manager said the 12 oz sizes were in in a small area the I didn't see. The bottom line is that the customer is giving tickets to the clerk for free items but is actually getting charged unless the customer catches the mistake. This is a poor business practice.
