Nice haul. The Bloodstone module alone goes for a good price on eBay. It *is* funny how some stores price their used stuff. One store I shopped at when I lived in New Hampshire would charge outrageous prices for some items ($25 for Keep on the Borderlands, you can get it for $5 on eBay) and nothing for truly hard to find items.
Why am I reminded of Tim Allen's routine about men looking for deals. Very nice haul indeed. I need to go treasure diving at my local stores myself now.
