[quote name='ninju D']Sweet! I just moved to that area. I'll check it out. Any other good game shops in Geebs?[/quote]
Welcome to the area!

Depends on the platform/game, I suppose, but here're
a few way too many random comments:
Shopko - Clearance stickers don't always reflect the real price, and it's hard to find a price checker except at Bay Park Mall. Prices seem to be universal across stores, so if you see it for $2 at one store and $10 at another, the $10 is probably wrong. If employees are feeling nice, they can also check their system to see whether a product is in stock at nearby stores. They tend to clearance games out slower than other stores (so if you're looking for an older hard-to-find game, you might have luck here).
Gamestop - We've got three (De Pere, Bay Park Mall, and West Mason by Sam's Club), so you should have a decent chance at using the gamestop.com Web site to find a store who has the game in stock. I haven't personally been impressed by Bay Park's customer service; must be related to their traffic.
Preplayed (on Oneida street, across from Bay Park Mall) - They've got reasonable prices sometimes. Price stickers are weird: Mario's Time Machine complete in box was $5; cartridge-only was $17. Classic games (e.g. NES) are not in their computer system, and stickers can't be seen without asking someone to open the display case. I'm sure there are some good $2 games in there, but it'll be hard to find when pricing is unknown. Urgh. They're the only store I know of, that keeps a waiting list for used games. Supposedly you can give them your name and number, and they'll call you when a certain used game comes in. That said, I haven't been called yet.
Mega Media Exchange (formerly Take 2) - All NES games are $4, and sometimes they're decent (e.g. Yoshi, Metroid, Ninja Gaiden 2, etc). They've got a computer system so you can look up pricing, but the interface is broken. (Try doing a search after a search, or using the "enter" key to submit your search, and you'll know what I mean). They've got the largest variety I've seen in the area, so definitely check this place out. They also have a rental program where you can pay monthly to rent out an amount of their inventory. ALWAYS check for duplicate copies of the item before you buy. (e.g. identical name-brand Dreamcast controllers were priced from $2 to $9; some SNES games range from $2-$5 for the same title/condition).
GB Games - A miracle every once in a while. Super Mario RPG for $30, Advance Wars DS for $12, Ice Climber for $4, but they're not overflowing with it. They seem to be cheap when offering $$ to buy games.
Video Game Kingdom - Reasonable prices, and really friendly staff. They also seem to offer more $$ for games than GB Games does. They've also got a lot of arcade game cabinets and tools lying around. Every once in a while they have the weirdo consoles (like Neo Geo, TI-99, Atari 2600, etc).
Goodwill - The west-side Goodwill prices games about $1 more than the east-side goodwill. I spent the last month routinely stopping by the east-side Goodwill to catch patterns in their stock. Found a few neat NES/SNES/GB/GBA/XBOX deals, but stock was pretty random.
St. Vincent De Paul - Sometimes you can find classic (2600/NES/SNES/N64/GEN/etc) games for $2 each. Not sure when the best time to go is.
Toys R Us - Their clearance bin can be interesting every once in a while. They've got a price-checking machine in the electronics department, which makes it easy to check for lower-than-expected prices.
Circuit City - I've only had luck here when being tipped off from CAG. Every deal I've had, has been due to the sticker price not matching the clearance price, and the item not being in the clearance bin. Good thing Circuit City prices are universal(ish) across stores.
Sears - I must not stop here at the right time. The deals tend to be pretty dry, no matter how many bored/wandering store employees might be staring at me.
Family Video - They're having some good clearance prices on games at the moment, depending on the store. You might find PS2/Gamecube/Xbox games for $4.95-$7.95. The problem is, most of these don't come with manuals. In a stroke of luck, I asked an employee about the manuals, and she was kind enough to go search the back boxes to find them for me. Now that's customer service. I'm used to being told "it doesn't come with manuals".
Hollywood Video - Every once in a while they have some $5 games (e.g. Kirby Star Race for Gamecube). Usually they include the manuals. The HV on Webster is closing soon of course, so you might find some clearance deals there. Suikoden IV was around $10 not long ago, I believe.
