Today I went to the supermarket and decided to buy some fresh apples by the pound. As usual, there are different brands for you to choose from and usually they are all set at different prices. When I went to the checkout to get them scanned I noticed that the cashier entered a different brand to calculate the total weight and cost. That would have meant paying more which I brought up.
I was just trying to imagine how many times something like this happens where people don’t check the receipt for this. Especially when you are buying a load of items as you are usually inclined to just assume that what they are entering is correct. Guess that is an example on how eyeing the item scanner display can help you save money from those kinds of mishaps.
