No issues. Firstly, I always use the self check-out. Secondly, big ticket stores like Kroger and Walmart will always honor any marked price and take it on the chin even if they knew it was a mistake a checkout. Asian supermarkets, even the big ones like H-mart and Great Wall/Jusgo will NOT. I once saw a NICE $16 pair of kitchen shears at Walmart that was in the $0.88 cent sale basket. I took it and it rang up $16. I said it was in the basket and they sent someone to check. There were 3 more pairs there so they said they will remove the other 3 but it will be 88 cents for me. The machine wouldn't let the cashier give that steep a discount so he just charged me 88 cents for a miscellaneous item on the receipt and let me take the kitchen shears. I love them to this day; those damn things cut through the bones in a chicken wing like they're baby carrots! On the other side of things, 2 weeks ago I was at Jusgo and saw that they marked some mushrooms $0.99 but were actually $1.29. My effing GOD! For 30 cents, I got into a shouting match with multiple cashiers and the vegetable section manager before the general manager was summoned and gave me that 30 cent discount!! All this with like 30 people in line watching LOLOL
