Oh, thank god for that. Generally I've lived without an Amazon account because they don't work outside the US. But this one, combined with the post that helped generate fake US addresses pushed me to do it.
Actually, now I'm pretty sure why Amazon would be upset when someone else copies their one-click patent. And the sneaky thing is, when you create a new account it's on by default!
You can get a refund within 7 days though if you do click by accident.
