Google Checkout $10 off $30 at Buy.com, CD Universe and DVD Empire
Google Checkout is running a nice promotion where you can save $10 off any order of $30 or more at selected merchants. For DVD fans the best choices seem to be Buy.com, CD Universe and DVD Empire. You might need to log out of your existing account with the stores to see the Google Checkout option.
If you need some suggestions for what to spend your money on Buy.com has a list of over 150 movies for $6 each and a pretty decent TV sale.
Unfortunately Google Checkout is only available to US residents so the millions of us living outside the US are out of luck.
