There are advantages for both the seller and buyer to eliminate the original price posted and the final sale prices:

Sellers may drop their price let's say 25% in private negotiations for a specific item. If they have other things they're selling, other buyers will think they can also offer 25% less for the other items. A seller may get a reputation for inflating their original prices for other things later even if he doesn't.

Buyers may become sellers of the same item if they decide not to keep it. They don't want the price they paid or originally advertised known.
