Hi guys, today I went to check Amazon wrt to my pre-ordered 650 from Target. Sorry but I just can't help but check my order's status at least once a day

. This is my first ereader after all, so I'm quite excited about it

.
However on checking, my pre-ordered 650 wasn't in my order history! When I finally decided to check my email there was a notification from Amazon stating that my order was cancelled because the product wasn't available from the supplier anymore. Ehh??

. If that's so why is the 650 still up for pre-order from Target on Amazon?
Has this ever happened to anyone else?
