Or will you check the receipt after payment? With us, he would have 1 prize for deceiving Interspar customers. There is a price written for the goods on the shelves, but more expensive is charged on the cash register. Sometimes it's a few crowns, other times larger amounts, but it happens to me with almost every purchase, especially when the holidays are approaching and people are shopping more. I always complain right away. Not that I was so interested in a few ducks, but in principle. Either the difference in price will return to me, or they will start to make excuses that I looked wrong and they make a fool of me. In that case, I'll say I don't want to and I'll get the full amount back.
