I just thought of a two step idea that could help people find stuff in the sales section easier. First, people who start a thread in a sale section get the power to close that thread (for whenever the sale is terminated for whatever reason). Then, a search option would be added to look in only open threads, closed threads, or both. This could allow commonly sold items that have been sold already to be eliminated from a search someone's doing for a part that's actually still for sale, or they can still search through all of them or just the closed ones to get an idea of how much whatever parts are selling for.

Thoughts? Usefulness? Feasibility?
