The last chance for glory, for fun, or to be a filthy scapler.

Amazon was the last retailer in the United States to post their availability for the group of Amiibo releasing tomorrow, and they have adopted an unusual release strategy according to an email sent to those who signed up for product notifications.
Rather than take preorders, Amazon has elected to post the Amiibo on release day and at a random point in a half hour period beginning at 2pm PT/5pm ET. Each Amiibo will go up for sale roughly every 30 minutes. The starting times and order is as follows:
Each Amiibo will be limited to 1 per person in an attempt to prevent hoarding, and Amazon will disable the 1-click function on these Amiibo. The email recommends ensuring payment and shipping information are available beforehand, but does not mention what happens if ordering multiple Amiibo with standard shipping.
