Hi Murdo,
I got it as a sample, but their website says 14.95 Euros + postage. Ordering direct from Tankograd is an "interesting" experience because they don't take credit cards online! I know some book sellers over here like Avid Books sell them in £ sterling, but I've only ever seen them at shows so cannot say if you can mail-order them. Tankograd's own website offers a link to an outlet in the UK called
Bookworld who sell it for £13.99, but I've never dealt with them.
