Amazon is the absolute best online retailer there is!
I have only had one order cancelled, due to the item no longer being made, but other than that I usually get my orders within one day and no shipping charges using the Prime Membership.
They have had a notice on their site about FSX not shipping until late this week due to the amount of orders that have been placed, and I would have to assume that most stores anywhere have been limited to the amount of dvds they could buy for stock in the first production run. This sim has been on pre-order for awhile so those shipped first any order after that is first come first serve until they run out, no fault of theirs

And you know when Uncle Bill is amd at you, he will give you the BSOD finger. lmao!
