Antes que nada, muy buena onda la de ThiagoPE de ofrecerse a enviar los productos al exterior. ¡Muy buena actitud!
I live outside Brasil , and I have the same problem with the shipping cost with Livraria Saraiva.
There are other stores, with less shipping cost.
http://www.cdpoint.com.br/WebForms/CDNHome.aspx (is the best)
http://www.dvdworld.com.br (they send an e mail with the shipping cost, after you buy)
http://www.2001video.com.br (only via fax)
