Bus from Prague to Krakow

Hi all,

I am going from Prague to Krakow on December 29th, 2009, and would like to take the bus, as it is the cheapest method I%26#39;ve heard and is the same duration as the train. I cannot find any bus lines or travel info (prices/timetable/ticket info) on buses from Prague to Krakow.

If anybody could help steer me in the right direction IT WOULD BE GREATLY APPRECIATED!

Thanks so much!

Krissy
