About uBid's Game Room
uBid's Game Room is very popular. This is where you want to be listed if you want to sell video game related stuff.
The Game Room has separate categories for Video Games, Video Game Accessories, Arcade Games,
Game Tables and other games. Here's how you get to it quickly: From the
uBid Homepage, select "Consumer Electronics", then on the left hand side where it says "Browse Categories", click on "Game Room". Be warned, the game room page shows about 300 auctions or so, so it
can take quite a while to load.
What do all the icons next to the listings mean?

Consumer Exchange sellers are consumers who wish to sell their products using uBid's services.
Consumer Exchange sellers list their items directly, and create their own product descriptions, establishment of starting and maximum bid prices, and shipping.
If you were to sell video games on uBid, your listing would have this symbol next to it.

These are auctions offered by uBid Preferred Partners which are established businesses that sell video games or other items and whose performances
are monitored to ensure that buyers receive the appropriate uBid service levels.

This symbol marks "direct products", ie uBid products that are direct from manufacturers and distributors and are backed by uBid's return and warranty policies.
Listings with this icon offer you the opportunity to purchase it outright at a fixed price instantly, without waiting for an auction to end. This means that when you sell your games,
you can simply ask for a fixed price.
