With Christmas right around the corner you may be giving your budget a look over for some extra spending cash. Today I wanted to dig a little further on the very easiest way to come up with some extra Christmas money — selling your old stuff! Selling your old stuff can kill two birds with one stone. First you get the benefits of extra money and secondly you get rid of your clutter. Not to mention, out of all the ways to earn extra money selling what you already have requires the least amount of effort. If you have a pile of college textbooks sitting around you may be able to earn a small fortune. BookScouter — BookScouter is a textbook buyback comparison tool. From there you can select the best offer. What if you have other types of books sitting around like fiction or personal development books? You can sell those too! They are very particular about the condition of the books they accept.
