I'm now seemingly at the very end of the order process, clicking the 'confirm purchase' button, the wheel turns, then nothing. Sometimes i have a popup with an obscure error code, sometimes not. It feels like doing a bitcoin transaction :P
Good luck, I am at the same spot and I doubt I am going to be able to get it to go through. The page on my phone is actually freezing up totally and the store won't load at all on my PC.
