Saving on Public Transport in Germany

In this modern digital world, information is everything! Yes, and it's a good thing we have all the information we need right smack at the tips of our fingers. One advantage of free and accessible information is that it helps us a lot on our travels and stuff. I heard of this travel tip in Germany which would make your trips as cheap as a lemonade drink in America! But you have to use actual public transport systems and all, you know. This is because gas prices have a rather global pricing system.
