Can you be charged a different price at the register than on the sales tag?

Yes, you can be charged a different price at the register than the price on the sales tag due to various factors such as pricing errors, sales promotions not being properly applied, or changes in pricing that haven't been updated on the tags. In many places, retailers are legally required to honor the lower price if a discrepancy occurs, but policies can vary. It's always a good idea to bring such discrepancies to the attention of the cashier for clarification or correction.
