Using Blue Nile Promotion Codes

Blue Nile offers discounts and special offers through both text links and banners as well as coupons and promotion codes. If you see an offer on promotioncode.org associated with a text link--the offer will say "Click to Redeem", simply click the link and make your purchase through the window that opens on the Blue Nile web site. The discount or offer will appear upon checkout if your purchase qualifies. If the offer is associated with a coupon or promotion code, simply click on the code and shop through the page that opens on the Blue Nile website. Enter the code at checkout to see the updated discount price or free shipping offer if your purchase qualifies.

Codes that appear on promotioncode.org as Staff Picks (those stamped with a Staff Pick yellow badge, as opposed to blue Community-Submitted badge) have been provided to us directly by Blue Nile. Other codes may be submitted by our community of users as with any electronic bulletin board. Because of the volume of these user-submitted codes, they are not tested, nor guaranteed to be valid by promotioncode.org. These codes appear with a blue "Community-Submitted" tag. Be sure to read any comments associated with such codes before trying to use them. You may also encounter offers that are labeled "Expired". These are codes or other offers for Blue Nile which have previously expired, or which our community of users has voted down over time although they might still be valid.
