Buying Books from Poland

Hello everyone,
I'm trying to buy a Polish edition of a book, though am finding it unbelievably difficult to find any stores online in Poland that will ship to the UK. Does anyone know either the reason behind this or know of any online stores that will ship here?
Kind regards
Kelvin

They all accept Visa and they all are shipping their books via Poczta Polska - so I don`t see any big deal why any of those and other sites would make problems becaouse of shiping their books abroad..
