Gamestop is a good store to browse for video games--they have an extensive selection of games for many systems, including Gameboy Advance, Xbox, Playstation 2, and Gamecube, as well as some of the older systems. They also carry the video game consoles, controllers, and memory cards, as well as strategy guides and video game collectibles.
You can find new and gently used video games here, and you are also encouraged to bring in your own used games to trade in. They also have a customer loyalty program--for the price of $10 per year, you get a subscription to their monthly magazine as well as a discount card good for 10% off used video game purchases.
Gamestop can be cheap or expensive, depending upon what you choose to buy. In some cases, if you are buying a new item, it may be better to shop around for a cheaper price. But, the selection of used games here can't be beat, so Gamestop is a must-stop for video game enthusiasts.
