I had one of those click to finalize order, then ended up back in the cart moments, but I was in such a hurry that I can't swear that I didn't click the wrong button. I've always used PayPal for payment, and haven't had any problems with that part so far.

I also experienced that initial "Sorry all sold out" thing some folks reported, but I assume that was because I got into the item before they were released for purchase. I wasn't the first to place an order, but I think I was pretty close -- I was F5ing and jumped on them as soon as they appeared.
