Reply #4: Don't be so sure about the ones with good policies being honest.

One of the major supermarket chains has a very good policy (I don't remember the details) but it's because of a court agreement that resulted from them being so bad and dishonest.

I've been checking receipts for about 15 years, and my experience is that drug stores and supermarkets are the worst. At least 95% of the errors are in the store's favor, so it's not honest mistakes. Honest mistakes would balance out. The number of errors rises and falls with the political winds. When the legislature is talking about it, as they do periodically, the errors disappear for awhile. When they think no one is paying attention, the errors come back.
