Picked up a couple of nice Sega items pretty cheap:

$20 for Ghouls 'n Ghosts, $25 for Terminator.
Also, a manual for my NES DK:

Found it in a basket of loose manuals for $2 at the same store as the two Sega games.
Now that Goodwill and other thrift stores are really starting to price gouge for their video games, I'm finding better deals at actual game stores. One particular Savers store has had several NES & SNES games on their shelves (actually in a glass case because they think they are gold) for months. NES & SNES carts should sell within days at thrift stores, but unfortunately the employees clearly don't know how to price them. They are obviously going by Ebay Buy-it-now asking prices, which are generally twice the actual value. Nothing I hate more than thrift stores charging top dollar (plus sometimes a premium on top of that).
