All I want is a Toon Link, and not for the $40 scalper price. IS that too much to ask? I mean they make all of these new games, with amiibo functionality, but good luck finding any of the amiibo for it for $12.99. I mean, I just want Ike, Lucina, and Robin because of FE Fates, yet no store within a 100 mile radius has it. I am also picky and want all US amiibos and not Japanese ones, personal preference I know but still. They should trickle out some series 1 and 2 amiibos a little at a time, so those of us who want them to own them have a chance.
I get what you're saying, and there's still a few amiibo that are hard to find. For the most part though, the stock issues are in the past.
But keep in mind, selective preference will cost you. That's just how collecting goes. You may not consider yourself a collector, but when you say you only want US amiibo, when there is literally zero difference between regions other than packaging (which shouldn't matter if you truly want to use in Fates), you're effectively in the same category as a consumer.
Once you toss the packaging, there is no evidence the amiibo came from a specific region. With that in mind, how badly do you want to tell yourself "These were purchased with NA packaging". More than you want to enjoy them in Fire Emblem?
