For anyone who has never heard of Slickdeals.net, they can be an occasional good source for low priced stuff to sell on eBay.
Granted, your not going to get rich or get a steady stream of products to sell but they are good for the occasional hit for some quick money.
Add the site to your Bookmarks and check them out every so often.
Right now there is a thread on there about getting an 8GB Ipod touch for 99$.
I have made some hits there with a printer which I netted 75$ and some other goodies.
I sold the printer on Cragislist.
I also got some great Harddrive deals which I sold on Craigslist too.
Again, not a steady stream of income but good for some fun.
