If you're a Nintendo 3DS owner and have been looking for an excuse to strengthen your game library for the system, Best Buy may have just provided the perfect excuse.

The retailer is hosting a sale this week for Nintendo's first-party 3DS line-up, offering a buy one, get one sale. You can snag two games for the price of one, choosing from such games as Mario Golf: World Tour, The Legend of Zelda: A Link Between Worlds, Disney Magical World and a number of others.  Individual games are priced between $29.99 and $39.99. You can check out the full list here.

The sale has already left a huge mark in terms of popularity, as a number of the titles aren't currently available for shipping, including Pokemon Y, the new Zelda game, and Bravely Default. However, there are plenty of others available, and you can either ask for them to be shipped, or picked up from a nearby store. The sale ends Saturday.
