Ah, OK - I see your point, Globaliser. It would certainly be annoying if different addresses were not permitted, although I suppose were such a system to be in place then card issuers to allow customers to notify them in advance of potential delivery addresses. Some retailers (I think Play.com was one of them) only allow delivery to the billing address - sometimes just for the first order, sometimes just for orders above a certain value. This can be quite annoying if you're not going to be in at the billing address to receive it!
