Store clerks and companies make mistakes sometimes. Also, sometimes signs and tags will get mixed up customers. Usually if the company is At Fault for a pricing error, they will print a retraction. If the clerk is at fault, sometimes they can override the price and sometimes thy can not. It all depends on the company rules and the clerk's position (manager, etc.). Often a store will agree to override a price if it is marked incorrectly, but this is usually done for customer satisfaction as they are under no legal obligation to change the price.
