Last semester, I was really out of money when finals were over. I got just enough funding to last through the tests. Luckily, I was sitting on a goldmine with my textbooks. Three months down the line I had forgotten how much I paid for these things. I found a great place online to sell textbooks. All I had to do was print out a shipping label and put my old texts into a box. In a week or so, I got a check. It really came in handy.
