Yes yes yes. Would be very nice to get some cash for stuff like extra raids drops, rods, oreo pieces, hulk pets and other rare drops. Kinda hard to get cash on ironmen and there is no joy in getting these drops anymore if you already have them or better. By making it an sell-only shop at the ironzone, these items wont affect the eco. The cash doesn't have to be near as good as you would get in the pos, but should be nice enough to stimulate pvming monsters which won't give you updates.
