Amazon could always just wait for confirmations if the order is large enough. Double-spends cost a lot to pull off. So if you're doing a large transaction, you're going to want it "settled" in the blockchain for about an hour.

The problem here is that neither you nor I can envision every possible way to exploit Amazon failing to confirm transactions of any size.
