KMa s.r.o. – Levné knihy is a Czech publishing company specialized on publishing and selling cheap books, especially classic literature with expired copyrights. Now they publish cheap movies on DVDs as well, for a price of 3-4 €, that is about 1% of common salary here and easily affordable.
They publish various kinds of movies, including large selection of excellent movies by Ingmar Bergman and Akira Kurosawa. Thanks to them I can watch movies on DVDs for the first time now.
