Yes, You are:). As far as I know there are no timetables covering Poland online. You need to find eg PKS Warszawa website, or PKS Kielce... PKS is not one large company covering all areas of Poland. There are dozens of PKS's covering some parts of Poland (if not late or cancelled).
I know , but its a 20 minute walk and its my day off so today I am proud to be lazy. I think I will just delay my trip to Poznan and go next week. I checked PKS torun ( where i live) and It doesnt say anything about going to Poznan. People say buses are really bad here but all mine have been on time:) IM sure it will be cancelled tomorow now and I will be late for work.....
