Use redemption code BRADSDEALS10 to take a rare 10% off at best-of-breed online jeweler Blue Nile (this does not apply to diamonds with "build-your-own" jewelry because the prices are already so low). Blue Nile is the largest online jeweler, has sold over 150,000 engagement rings. They buy diamonds through the same wholesalers that Tiffany's does, but can sell for 20-40% less. They have a very well-explained website (see their wedding ring guide, for example), guiding men (mainly, including myself) to an informed purchase without the sleazy salesman. FedEx Priority Shipping is free on all orders, there's no sales tax and a fully guaranteed 30-day return policy.
