NoA
tweeted a couple hours ago about a new Club Nintendo reward they just put out. It's a game case that holds 18 DS/DSi/3DS game cartridges, and it comes in a
Zelda flavor and an
Animal Crossing flavor. Either one you get will set you back 400 coins but the case will come with 3 reversible covers, including a 3DS-themed one and a Mario-themed one in addition to either the Zelda-themed one or the Animal Crossing-themed one.
It may sell out fast, especially the Zelda one, so if you live in North America, get em while you still can. The recent A Link Between Worlds Poster set sold out pretty fast and so did the multicolored 3DSXL charging docks (although I think those are now available in NoE's Stars Catalogue).
