Never understood why people struggle with the bagging area thing. You're doing something wrong. Here's a hint: Every item in the store is weighed, and the bagging area has a scale on it that measures that weight. If you accidentally put more or less weight into the bagging area, it'll complain.

Scan, immediately bag within 3 seconds, and don't let anything touch the bagging area, not even your hands. Utilize the "skip bagging" button for items that take more than 3 seconds to bag (but don't hit "skip bagging more than 3/4 times or it'll complain). Immediately remove any excess weight (such as your arm or a bag) after bagging. I promise you'll almost never have another an issue again.
