Gotta love ebay!
Well, sometimes at least. I was looking for some Pratchett books. My collection of hardbacks was 3 issues behind. In a dutch bookshop a single book can easily set you back 30 euros. Even at bol.com you're lucky to pay 20 euro for one. Via ebay and thanks to the current pound-euro rate I got Thud, making money and wintersmith for only 33 euros including delivery. And all of them with Paul Kidby's excellent artwork.
