Google’s popular Nexus 7 tablet is selling out and it isn’t easy to find since retailers began selling it on Friday.

PC World reported that the new Android tablet is available at Sam’s Club and GameStop stores, but that was based on just spot checks at random stores. A variety of online retailers such as Staples, Office Depot and Best Buy are evidently sold out. It isn’t clear when the retailers will get more in stock.

GameStop has a promotion where it will give you an extra 30 percent bonus on trade-ins of games, gaming systems and accessories. That means if you trade in a game system worth $80, GameStop will give you $24 toward the Nexus 7 purchase.

The Nexus 7 sells for $199 to $249, putting it on a square footing against the rival Amazon Kindle Fire tablet. It’s a lot cheaper than anything Apple currently offers. The Nexus 7 has a quad-core processor, the latest Android version 4.1 Jelly Bean, and many other exciting features. It is being built by Asus.
