warshawlawI would probably not only not tell the li'l ol' lady she had a Wagner in the box, I would inquire whether she could do a little better on the box. If the seller sets a price on her wares, it is her tough luck if she set a low price; next time do your homework. Sorry to inject a little reality into the debate, but I don't see the need to give up my hard-earned competitive advantage (knowledge) in an arms-length transaction.
I fail to see the difference between the example specified and an ebay seller listing a rarity as a common or in the wrong category. I haven't seen a rush of folks here emailing sellers about those mistakes; I have seen a lot of people crow about the great deals they got that way and a lot of others complaining that deals like that were "outed" before the auction close.
