Hi there! Finally got back to this. Yes, like Amy said, I can send/receive packages thru the US system. We can either try the on-line ordering, or have someone buy and ship things to me. Then I can forward them thru the German postal system. I haven't looked into the costs for German shipping to the UK yet. I guess that's why I never got back about it before.
Although I wouldn't be able to do this often--I don't want to get in trouble and lose my mail privileges.
I'll have to find out some shipping costs and you can decide if it's worth it. What brands/items would you be looking for? Let me know.
