Check out the list of deals for Google Checkout users. Here’s an example of the savings: Buy.com – get $10 off orders over $10 (for new buyers only). There is also free shipping and frequent flyer miles to be earned (make sure to view the tabs because they’re easy to miss). You have to register and then you can earn 2 frequent flyer miles for each $1 you spend with Google Checkout through December 31, 2007. They cap the miles at 10,000 and it’s for US residents only.
