I think there should be a Price Check section in the Non-Virtual Items thread. I don't know how much some of my stuff I want to sell is. Like my Nintendo DS Lite Pokemon Limited Edition, or my PSP 2000 Silver.
I don't see why not, although I don't really know how active that market is, so that sub-section may be pretty dead and would be easier to just look up on google or e-bay the price of that item.
