Historically Kapow and InDemand charge about the same with TFS-Express often coming in slightly cheaper, sometimes TFS-Express will offer a deal to existing customers that will come in as low as Japanese retailers. To be fair, ID's price is below MSRP (24,000 yen/£174) so it's not like they're taking the mickey or owt. As i understand it AJ charge you some form of import fees on checkout which will at the very least push the price up to AE levels. Then you have to run the gauntlet of HRMC, I cant see a company like Amazon under-declaring on the customs declaration...so Im skeptical it would work out cheaper for UK buyer. Plus it's Amazon and they are evil.
