One of my friends has a TON of MAC that he wants to sell on Ebay (he's a former employee and has collected a bunch of LE items, tee shirts, jewelry, etc). He has a particular eyeshadow called Zone that he wants to sell. He told me it was produced in very limited quantities (it's in the screw top container and was produced a la Judy Blue) and he has no idea what to price it at...any suggestions? Anyone even heard of it?? TIA!
