Ok, this is a strange one 
I have a friend who's just gone back to the US recently and I wanna send her a valentines day card. simple enough so far
The thing is, I want to send it so there is no identifying UK mark on it, so things like UK stamps, rubber date stamps etc can't be on the envelope. basically anything that points to the UK.
Is this even possible?
The only way i can think of is to send it to someone else in the US in a second envelope, get them to open it and then post the first envelope with the card in to her address for me, only problem is I dont know anyone else that lives there lol
possible ideas?
