Yes, I buy discounted items because a) I don't have a lot of money and b) the items are usually in perfect condition. I'm also one of those people who takes the receipt with me and takes another look at it when I get home. Unfortunately, I notice that it happens again and again that an item with 1/2 price (or simply reduced) is still on the slip at the normal price. I try to place the items on the conveyor belt in such a way that the cashier can see the receipt and react accordingly. However, this doesn't always work.
I understand that the cashier is under pressure and can make a mistake, but it's also very unpleasant when you stand there with the receipt before packing and then have to check whether the discount has been granted. Conclusion: you end up paying the full price and are annoyed.
I wonder if there is no other way? With self-scanning it also works with a new code? I often shop in small stores where this is not yet available and I have to go to the checkout. Is there really no better solution for Migros?
