This needs a drop...Not sure if right range, maybe 2.2-2.6 would be better, don't really know...Also first suggestion

Almost 2 pages on outpost, some sell for more than current price and few are in sets (1-2) and blahblah, some want items (bad deals for the buyers). That is the reason for only some links...
