It's quite a few less miles but a much better deal to shop on Blue Nile. I've been pricing the engagement rings myself last couple of months and Blue Nile is a much better product. Overall they always have the better price on a comparable diamond. You still get the Delta miles (from Andrew Crams Page) and whatever credit card miles you want and then call someone like Discover and do a transfer for a 0% life of the loan rate. If you do a google search for Blue Nile discount you can probably find atleast a 10 percent off coupon. It's a great source for diamond buying education also, I never knew how much was invloved with picking a good diamond. Good luck, hope it works out for you.
