Låna smart. Köp nåt dumt.
Problem
Many people are not aware of the wide selection of products the library has to offer. Neither are they aware of how much money you actually can save by borrowing books, video games, audio books etc. from the library instead of buying them new.
Insight
It is both smarter and more economical to borrow things from your library instead of buying them in a store. But simply urging people to think smart easily becomes snobbish and boring.
Solution
The more you borrow from the library, the more money you will save. Money you are free to spend on stupid things that may not be either necessary or practical, but that make life a little more fun.
