How about an NPC trader that will exchange any and all premium wallet items for 1s. Ie 1 rusted dwarf tool for 1s, 5 rusted dwarf tool for 1s, 10 rusted dwarf tool for 1s, 25 rusted dwarf tool for 1s.

This would give me a way to dump stuff I don't want stuck permanently in my wallet (read festival tokens and low level barter stuff I may accidentally gather on my travels thru middle earth) without having to add a delete feature to the wallet.
