Found some decent stuff today:
Goodwill:
Doom II (PC) Big Box, 3.5" Floppy Disc version: 75 cents
Playstation Mouse with mousepad: $2.50
Xbox RF Adapter NIB: $3.00
Thrift Store:
System Shock 2 (Jewel Case/CD) PC: $1.49
PS2 Slim (with spongebob game inside) AS-IS: $5.99
GBA system: $7.99
Halo 2 (Xbox): $5.00
In the mail today:
Code of Princess from Amazon: $0.00
Tales of Graces F Special Edition (PAL): $40.00 shipped
--So the PS2 slim I got from a Goodwill about a month ago, ended up not powering on so I sold it on Ebay for $50 shipped (paid $10 for it), and hopefully this PS2 slim has the same result online). System Shock 2 surprisingly goes for quite a bit disc only. About $30+. Playstation mouse (complete in box) goes for $25+, and Doom II maybe $30 and up. I think I did pretty well considering.
