It would be nice if the Trading Center was organized from lowest price to highest price. Yes, if you were just looking through what’s being offered it might take a while to find the expensive stuff, but most people don’t want the expensive stuff and want to see what’s being offered for cheap. It would also make searching for items that are frequently sold easier because you’d immediately find the lowest price. I don’t know about anyone else, but I think that would make life easier :)
