I find it kind of funny how people on the internet went from complaining that the quality of Amiibo was so poor that they weren't worth buying and that they're overpriced for what they are to complaining that they're selling out too quickly that they can't find them in stores.
Hmm... some people might have made those complaints.
Mine were more along the lines of:
(1) production models are significantly worse than display models, with some poor decisions (like Link's yellow stick) standing out as particularly unfortunate
(2) they are slightly overpriced, but that's not a huge surprise given the source
(3) distribution has been very poor and it's frustrating for anyone who doesn't want the main Nintendo mascots to be driven to an absolutely ridiculous scalper market to get the figures they want, while NoA and retailers make contradictory and unclear statements about whether specific figures will be reprinted/restocked
And which one of those complaints are wrong?
None of those complaints are wrong, but the rhetoric across the internet in general, not anyone in particular here, seems to be a little more extreme than your reasonable complaints.
So why is everything well stocked in Japan and not here? Are there retailer exclusives there or is that just a US thing? Is it NoA being completely incompetent here and NoJ having a clue or is it retailers here being less willing to order stock and devote shelf space to something Wii U based? I can kind of see retailers not wanting to have tons of of lesser known characters that they think they'll end up stuck with and Nintendo not wanting to have warehouses full of figures they can't get on store shelves, but after seeing the success they've had, it is kind of bizarre that they haven't said that they're going to produce more of something that people clearly want.
