When I was in Madrid earlier this year, I visited many antiquarian and secondhand book stores, but some how I missed La Casqueria, Libros al Peso. Situated in the recently renovated Mercado de San Fernando in the up and coming Lavapies neighborhood, the book shop has been getting quite a bit of attention for their policy of selling all of their secondhand book at the flat rate of €10 per kilo. With the Euro hovering near the $1.20 exchange rate, $6 a pound for most titles is a real bargain.

Mercado de San Fernando is located at Calle de Embajadores 41 not far from the Lavapies Metro station.
