1) There is no such thing as a free lunch.

This is often true, but not as much as everyone thinks. The statement means you pay for everything one way or another in the end. I will agree that this is technically true most of the time. But this doesn’t stop me from looking for freebies anyway, but every request for free offers or registration for a free service takes some time and some effort as well as giving up some privacy. However, I will say that if you have the time, enjoy doing it, and are careful the cost becomes negligible.
