Coming from an Amazon rep...
We're going to be putting them (amiibo) up the day they launch (9/11/15). They'll go up during normal business hours. We've been pretty successful doing it this way for wave 4 and Palutena, so no reason to change what's working for us.
If you want to purchase some Wii U or 3DS games digitally, it looks like Amazon has got what you want. The following games are available for purchase digitally.
Hyrule Warriors: The Hero of Hyrule Pack
Kirby: Nightmare in Dream Land
The Legend of Zelda: The Minish Cap
Mario Kart 8 Bundle Pack
Yoshi’s Island: Super Mario Advance 3
Kirby Fighters Deluxe
The Legend of Zelda
Punch-Out!! Featuring Mr. Dream
Super Mario Bros. 3
It was rumored...then announced...then put on sale and now it's gone. Believe it or not, the New 3DS XL: Hyrule Gold Edition that went live on GameStop's website earlier today is already sold out. We have no word on restocks, but let's hope they happen at some point. Unfortunately, it seems like the only other way to grab this sucker right now will be through resellers.
