Free samples from eBay?!
http://extras.ebay.com/ and scroll down to click on "free samples" (left side of the page). It's almost like a master list of all the free samples currently being offered! You can also print coupons here, but they look like they're the same ones available at coupons.com (and it may even print through them...). Also, if you are crazy about free samples, BE SURE you check out http://www.mysavings.com/ and sign up for their newsletter. There are more free samples listed here than ANYWHERE I've found. Just don't complain when they're overrunning your mailbox! Ha!
