Make sure to pay attention to the prices scanning through. I know there have been many times when I have looked at my bill after I got home and realized they over charged me for something. I'm not sure how it works for going back to the store and pointing out an error, I think you have to point it out at the time of purchase.
I know Save on Foods, Superstore, Extra Foods and Shoppers Drug Mart participate. There are lots more, but those are just the ones I know for sure. I think Walmart did, but not sure if they do anymore. It's always worth a shot!
