In my opinion, not good. Even most US internet stores don't handle international shipping. Your best bet is to go to a UPS Store (formerly known as Mailbox, Etc) or a Fed-Ex Kinkos and talk to them. They are very common.

Also recognize that if you ship the item into the UK, you are looking at duty. You might want to pull the camera and ship all the ancillary stuff. If you go into one of the electronics districts, one of the independent companies might be more accomodating. Circuit City will have a hard enough time trying to put your phone number into their computer.

Just my two cents. Unfortunately, my country (the US, not the UAE), is way too provincial.
