Half.com is owned by eBay but has a much more specific purpose: It lets you sell books, movies, CDs, and video games at a fixed price. You enter in the product’s UPC code and come up with a price, and your listing appears on the site. Payments are made once a month via direct deposit into your checking account.
Half.com doesn’t charge a per-listing fee, but they do charge a commission that can get pretty steep – up to 15 percent per item, depending on your listing price.
Best for: Textbooks. A good portion of the site markets textbooks exclusively.
