Amazon has put up a listing for Super Smash Bros Digital Complete Pack for both the Wii U and Nintendo 3DS. The listing is only for a digital download code for the game and contains DLC Collections 1, 2, and 3.
Purchased separately the cost amounts to $81.92 on the Nintendo 3DS and on the Wii U the content costs $101.92. The Complete Pack saves you a very small amount, as the listing for the 3DS version is $79.99 and Wii U at $99.99.
If you somehow haven’t already jumped on the Smash Bros train this would be the perfect time to grab a significant chunk of the downloadable content released for Smash Bros, though don’t forget there are also new stages and Mii costumes not included in the bundle.
