PLEASE VOTE ON THIS GUIDE AT THE BOTTOM!!!
I recently imported an expensive swiss watch from the USA for half the UK RRP!!!!
I simply found the watch I wanted, looked what was on offer (new) on eBay in the UK (both private sellers and shops), then searched on international sellers.
I found my watch for sale on eBay (US seller) but was unsure what to do as the seller only accepted bank wire international money transfer and didnt accept PAYPAL internationally. I looked into this and found out it only cost £20 to send it from my bank.
The seller was emailed numerous times to ensure what I was getting was correct and that I had all of the neccessary details to pass to my bank. I placed the order and did the transfer.
5 days later I was wearing a brand new Tag Heuer F1 chronograph watch.
I wont say whether or not I paid any import taxes or duties...... all I can say is I am very, very happy!!!
I would recommend looking into this yourself.... but beware.... be prepared to pay 25% of what the watch is worth in taxes and duties if you get caught. I allowed for this and it was still cheaper than buying in the UK.
Just makesure you know what you are getting (ie - P&P, warranty, paperwork etc etc)
