Blue Nile has free Fedex shipping and 20 off $50 by using PayPal. It may be a good idea to start with the $100 and Under Section. For seven years, Forbes Magazine has listed Blue Nile as its favorite online jeweler. While the terms of the PayPal discount state that you will get the $20 deposited back into your PayPal account by 1/31, the last time we did a similar deal, it took only 4 days from the date of purchase. Offer is valid until 3pm ET on 12/22.
