Just a quick note about half.com. I discovered this recently and am still learning the ups and downs. A service owned by E-Bay, www.half.com allows one to easily list and sell or buy DVDs, music CDs, audio books, books and textbooks.
In the first week I started using it, I sold 6 movie DVDs. They don’t go for much, but the process is easy. One could argue I might get better value from a tax exempted donation.
I encourage you to take a look. If you have kids in college, you know the exorbitant pricing of textbooks alone.
