Nintendo Store offers its factory-refurbished Nintendo 2DS Portable Gaming System in Crimson Red, Crystal Blue, Crystal Red, or Electric Blue for $60 plus $5 for shipping. That's $35 under our refurb mention from last summer (which was bundled with a game) and the best price we've seen for a 2DS. (It's currently $35 less than the cost of a new one.) It's fully compatible with 3DS and DS games but doesn't play games in 3D. A 1-year Nintendo warranty applies.
Nintendo offers its refurbished New Super Mario Bros. U and New Super Luigi U for Wii U for $30 with free shipping. That's $3 under our mention of a used copy from last winter and the lowest price we've seen. (It's also $35 under the best price we could find for a used copy.) A 1-year Nintendo warranty applies.
Nintendo offers the factory-refurbished Super Mario 3D World for Wii U for $29.99 plus $5 for shipping. That's $3 under our used mention from March and $13 below the lowest total price we could find for a new one. A 90-day Nintendo warranty applies.
