I've strongly considered some older/more elaborate/more obscure games at sales recently, but the waves of pop-culture collectibilia have hit this town hard, which is why I consistently do so well with *very* nice jewelry here while navigating stacks of comics and crappy records and half-complete board games priced at $5-10+ EACH. I'm hesitant to buy anything that's used but stuff that's still sealed always commands a premium so I've stayed away thus far.
However, I need to remember that shallow flat-pack-type boxes such as those used by Danbury/Franklin Mint are always worth peeking in to! You could find sterling plates or personal-sized Pentagons or god only knows what else, can't really go wrong at two bucks a pop IMO. Nice finds, and thanks for reminding us to leave no cardboard lid unturned.
