VAT - value added tax. If you are buying from the US you don't pay it. Once you enter your address for shipping you end up paying for the item without the added tax so just look at the tax excluded prices.
You just solved one of the biggest headaches I've had in years!!
That's where I got my Shoubu. About the same size as a barber hone, maybe a little longer, with tomo nagura for I want to say a little under $100 all in. They don't seem to last long, so you kinda have to strike while the iron is hot.
