Scoring free textbooks
Why is it that education is so darned expensive? Education is the key to a better life, but you can only become educated if you have the money or means to get a loan. It sounds like one huge pyramid scheme to us. But you can totally exploit the education scheme by doing what this guy does.

If a bookstore offers a grace period for their books, scan all of its pages and merge them together, then return the book to the store. Now, you’ll have an e-book of that $500 book that your professor wrote and forced you to buy. Just don’t share that e-book online for other people to benefit from. That’d be wrong.
