GameStop is expanding its Android tablet lineup, adding the tablets to more than 1,600 stores nationwide.

The gaming retailer is now selling tablets like the Asus Transformer Prime, the Samsung Galaxy Tab, and the Acer Iconia.

GameStop promised that tablets sold through its stores will come equipped with "valuable extras," such as free games like Sonic CD and Riptide. The gadgets will also have the Kongregate Arcade gaming app and buyers will get a free issue of Game Informer Digital.

What tablets are on sale? The Asus Transformer Prime is available now for $499.99, while the 10.1-inch Asus Eee Pad Transformer is $349.99. The Acer Iconia Tab A200 will be $299.99 now through June 2, while the 7-inch 8GB Acer Iconia is $229.99. The 10.1-inch Samsung Galaxy Tab 16GB is also available for $399.99, and a Toshiba Excite 10 will set you back $449.99.

If your local GameStop is not selling the tablets, you can also purchase online.

GameStop also sells refurbished, first-generation iPads starting at $285. As GameStop noted, "cosmetically, the screen and body of the items show some signs of scratches, scuffs, or other wear typical of normal use."

The store allows shoppers to purchase new good with trades of games, consoles, or old iOS devices.

GameStop first started selling the Acer A100, Asus Transformer, and Samsung Galaxy Tab in 200 stores last October, and that now expands to 1,600 locations.

A month earlier, GameStop said it had selected the Android OS for an in-house tablet device with pre-loaded titles, but that has yet to be announced.

The move comes as more and more gamers are turning to smartphones and tablets for their gaming needs rather than standalone, handheld consoles. The Nintendo 3DS and Sony PlayStation Vita have seen somewhat sluggish sales here in the U.S., while game makers are increasingly showing off tablet-optimized versions of their games.
