I'm based in the UK and I had no problems ordering Midas, direct from Sideshow.. Midas was never listed by Forbidden Planet(.com) in the UK and the main authorised European distributor, charged an inflated price for Midas.. so I'm going to be ordering Python direct form Sideshow.
Note that Sideshow's courier Fed Ex, will pay the import duties and then bill you afterwards.. this means you get the figure delivered faster and to your door.. rather than having to wait for it to be processed through normal channels and then have to collect and pay for it at a regional depot.
To work out the import duty fee in advance, you take the complete US dollar price (figure cost and shipping cost combined) convert it to sterling (as an example, type.. change 350 dollars into pounds ..using Google's search) then 20% of that figure gives you the VAT charge, plus approx £11 for the tax processing fee.
So the 20% plus processing fee, is what Fed Ex will bill you.. bear in mind that because exchange rates fluctuate, working the figure out in advance is not an exact science.
