I think about a week or so. Can't remember how long the last order took. Doesn't seem to take as long as I sometimes think it will though....My latest order will take a bit longer since it is a pre order but, once it ships it won't take too long.
All of my orders from the UK had to been signed for, though. Not had to do that with orders from the US.
May I ask what it is you want to order that the US site doesn't have?
