You don't really need a UK dealer, Sideshow have a warehouse in the UK so delivery is about £14 for all of the items except the huge ones, for the huge ones I buy from Forbidden Planet UK. In other words Shell is spot on.
Kinda, it ships from the US first but because they ship a lot of stuff at the same time shipping only costs $28. Once it arrives in the EU warehouse you'll get Parcelforce tracking details.
