Would need some serious work for it to function, as I dont think the NPCs recognize if something is enchanted +12 or not, or if it's blessed, which affect the value. Also, people may have stockpiles of something that isn't know (eg owning 15+ xmas flame swords) which would just spam the store with these items that would be considered junk if too many wound up there. Stockpilers like these control the value of certain items.
