Legally speaking you're right. An advertisement, even a price list for specific items, is a solicitation for offers, not in and of itself an offer. He did not have an agreement with any poster, so no contract.Originally Posted by Zanzibarstar
Ethically is a wholly different question, and he did flat out lie to the other parties interested the second time, by his own admission. If he had just said "I'm sorry, but the item is no longer on the market", there wouldn't be an ethical issue, other then the price increases, which are quite debatable as an ethical matter. Quite frankly I come down on ranchnman's side on that, he made a mistake and was able to correct it before a binding contract was entered into. I find no fault in that.
