A MSN.com article lists the following:
2. DVDs and CDs
3. Little kids’ toys
4. Jewelry (TC: Uh-Oh)
5. Sports equipment
7. Software and console games
8. Office furniture

Addendum: As long as we are on the topic of "ten," here is Guy Kawasaki’s "Ten Things They Should Teach You in School," recommended.
