H&M 20% Discount Turned Out to Be 35% Increase In the Store

Just now 0 Good day, this morning we received a message saying there is a 20% discount at our Denizli Sinpaş H&M store. When we went there and chose a coat for my son, there were two different prices for the same coat. The size S was priced at 1649 TL, and the size M was priced at 1209 TL. When I asked the salesperson about the price difference, they simply said, "We forgot to put the labels; just take the product at the price written on it," and brushed off my concern. I went back to the cashier, and they provided the same response, leaving me no choice but to purchase the coat since my son liked it. It seems like the 20% discount was offset by a hidden 35% increase. Congratulations, H&M.
