Hey I Was just at a used book store buying some old Gamma World Modules and what did I see but a copy of the Jade hare sitting there for $5.00.  I took the stuff up to the counter and the guy added up the total and threw in the Jade Hare module for free     because I was buying some old stock.

What a great day

Good luck in your seaches

*sigh* the store that I used to have some pretty good finds at, Barbarian Bookshop in Wheaton, MD, sold all their RPG stuff to an eBay reseller (but not until LONG after I'd picked out most of the great stuff from their stock, 60% of what was left was White Wolf stuff that was only 2-4 years old).  Some of the best:  Dungeons 1-30 for about $60 ($2 each), Castle Greyhawk for $5, Dragonlance and Forgotten Realms Atlas for $7, and a few more.  Best deal I ever got on anything in any of the stuff I collect was a rare Cocteau Twins CD singles boxset for $15 (while it was going for $200+ on eBay).
Now, if I can just stumble on "Up the Garden Path" like that...  of course, you Brits are MUCH more likely to have that happen...
