A seller is allowed to ask whatever price they want, it is their item, and they do not have to sell it. Some are just testing the waters, they don't really want to sell, but they will if the price is right. I've done this myself on occasion. It all depends on how serious and/or motivated the seller and/or the buyer are. Some buyers offer ridiculously low prices, there are threads about that too. It's all just part of the game, no big deal.
