> In most American states the customer is entitled, by law, to the lowest advertised or marked price. The store must honor that price. Advertised by whom? If you mean advertised by the very store in which the customer is trying to purchase the good, that makes a lot of sense (in view of consumer protection /truth in advertising). However, the previous comment was about the MSRP - the manufacturer suggested retail price. While that's not an average per se, neither is it a mandatory limit. As the name suggests, it's a suggestion.
