Delivery services are extremely pressed right now, so things will be arriving slower than normal.About a month & a half before release, I tried to preorder the double pack from Amazon, but they were out of stock. We ended up finding and preordering it from Target.
Fast-forward to a few days before release. We check, and discover that my preorder from Target got... cancelled, or dropped, or SOMETHING. Hastily we scoured the web, but the only place we could find to quickly preorder the double-pack was eBay. Still, it was supposed to come Saturday or Sunday.
It did not. Nor did it come Monday, or today.
While everyone on the entire internet is talking about the games, showing off their post-game teams and posting videos about how to catch certain end-game Legendaries or take on the E4 a second time, I haven't even gotten to play the games yet.
If it doesn't come in the mail tomorrow, I'm going to buy a copy of BD myself from Amazon, spend the $$$$$ for same-day / next-day delivery, and my uncle can just get a refund for the double-pack he preordered for me when it arrives in late December or whatever.
That being said, I have heard of a similar experience at Target in which someone I know pre-ordered a Skyward Sword HD amiibo and it was abruptly canceled before she could get there. Employees at Target are fully authorized to cancel pre-ordered items without the customer's knowledge. She suspected the employee there did this to ensure he or someone he knew got that amiibo, and I'll bet the same thing happened to you.
