gamma0577If you go to transactions and the to customer support, you can request an adress change using the form (you will find the option there).
I did it for my preonic order, i think it took them like 2 days to change it.
So its fairly fast.
gamma0577Same as @massiker, he's correct.
I'm currently moving so I needed my address changed. Submit a ticket and in one or two days they'll change it.
