And it wasn't easy - you had to copy dozens of floppy disks, often people copied each disk 2 times, because out of 20 floppies one is bound to have read errors, if not more. It took ages.
But the prices were crazy - a game costed 60-120 PLN and people earned like 700 PLN per month.
Then piracy got much easier thanks to CD recorders and internet - but it changed nothing, because you can't go over 100% :)
Since that time piracy only got easier thanks to broadband, dvd-writers, usb pendrives, ssds, yet legal computer market in Poland increased many times and piracy is in decline. Mostly because of increasing salaries, and extras included with legal copies.
