We Had 400 People Shop For Groceries. What We Found Will Shock You.

42. It's not as easy as I it used to be.

Now that process are changing more frequently. It both makes it harder to remember - and - more likely that the shelf price won't match the check-out price.

I have a few more tricks that help - the store I ship at most frequently for large shopping trips has an app that lets me check out as I go, so I scan the item as I put it into my cart - and I can see immediately if there is an error. When I get to the cash register, my app transfers the list with prices to the register. If there was a discrepancy, I either go to a staffed register or immediately press the call button for assistance - depending on how complicated I expect the problem will be to fix.

This probably won't help you - but in stores where there isn't a self-checkout, I also keep a running mental total. If it is more than a dollar or two off from the register total, I start looking for what I might have been over- or under-charged for.

A quick way to catch most of the errors is to keep track of the temporary sale items. In my experience, that catches at least 90% of the errors.
