false advertising

why does a store advertise a product, at a price, only to tell you when you get to the store that the price was a \mistake""; at a promotional price; for a limited duration; to keep the same product on the shelf at a higher price during that time<br> If a mistake was detected; shouldn't the product be removed from the shelf for that period?<br> Is it OK for the store manager; Brady Govender; to maintain a POOR attitude;for a mistake that cost a consumer time and money to get to his store?<br> Was this all a ploy just to get customers to his store?<br> I wonder."""
