UPDATE (6:48pm): At this time, all Wave 4 amiibo pre-orders are sold out.
-------------------------------------
Due to very strong demand for the newest wave of Nintendo’s amiibo figures, GameStop is experiencing some technical issues with our website.
At this time, we are accepting pre-orders of amiibo in stores only while we resolve these issues.
We are working aggressively to resolve the technical issues as quickly as possible and expect it to be back online shortly.
