Where can I learn how to use this program?

I am looking for a new job, and a lot of the positions I have seen listed seem to require you to be able to use Prince2. Can anyone tell me where I might be able to find out more about Prince2 training courses? I want to find out where I can go to learn how to use the program without purchasing it first. I don’t want to spend any more money than I have to since I don’t know whether I will need to know the program in the end or not, but it definitely won’t hurt to know how to use it.
