The USA has a mail order law that requires an item to be shipped within 30 days of final payment or full payment. If not the company is required to maintain a hard copy of confirmation that you wave that right. And you can request a full refund any time. If refund is not processed within a set time period it is a 10,000 dollar fine, at minimum. But, if only a partial payment is accepted they can not be fined. There's some additional wording and it's a bit more complicated (I can provide info and links if anyone really wants it) but essentially that law is why places don't accept full payment on preorders that much.
Interesting...
