So, that controller gave me a weird "left with the receptionist" shipping confirmation. Ain't no receptionist around here. Then I noticed the invoice said "Amazon Customer, Gift Shipping Address." So I fired up Amazon chat, instant refund.
My new theory is when third party sellers (Amazon Warehouse Deals in this case) get stung with a price mistake, they're opting to give you a bogus tracking number and pretend it got lost in the mail. Happened with Walmart and that PS4 game a few weeks ago, too.
