Incorrect pricing

I visited the checkers store in canal walk on 28.11.2020 and stumbled across the rainbocorn kids toy. It was incorrectly priced and when i requested for them to give it to me at the price that i saw it for they said, its new stock so they cant give it to me at that price, the manager Selena Fortuin told me a customer mustve put it there or it was a different item. As far as i know the customer pays what he/she sees as this is done at other stores irrespective of the barcodes, because us as customers dont look at things like that we look at prices.
