I went to a Gamestop to ask if they had any Wave 3 Amiibos that weren't for pre-orders and got laughed out of the store before I finished my sentence....these Gamestop employees have been real shitty regarding Amiibos..
That was not a quick sell out in the screen print collecting community. It was up pretty much all day, which is like 10000 lifetimes. Quick sell outs are generally within seconds.
I got an e-mail from Best buy with a $20 Gift card to use from the black friday in store pick up thing....i used it on some Nintendo cards and the $20 actually turned out to be $50!

Appears to be only 3 of each one in stock BTW.
I just got a pre-owned Pikmin 3 for half off with this at a Gamestop location....but this included the Gamestop employee having to be on the phone for 40 minutes with the Gamestop power up rewards people...and then a call to the DM to honor it.....
