Best Buy is currently offering the 3DS XL for $170, a hefty 30 bucks off the usual price. The sale applies to both the red and blue versions of Nintendo's beefier handheld, and is available both online and in-store. This would be a good time to remind you that $30 can get you plenty of great eShop games like Cave Story,Sakura Samurai, Mutant Mudds, Crashmo and more.
