But, a neighbour of mine who sent parcels to his son in the US had a hell of a time a few months ago. (My neighbour is a project manager at an airline co and a longstanding international fedex user).
It seems that sending things to the US has become much more difficult in the last few years.
There are many courier companies shipping items around the UK and abroad - good luck finding one to do all you need.
Is there a forum on ebay or even QXL which might help?
