Online Shopping
Blue Nile pioneered buying engagement rings online, letting shoppers customize diamonds at bluenile.com, where checkout codes as online shopping or general retail. Ring purchases run large, so even a modest flat or online multiplier returns real value on a single order. Jewelry carries no dedicated bonus tier, making a high everyday-earning card the sensible choice here.
Picks without a tag earn at Blue Nile both in-store and online. Watch for theOnline onlytag — those bonuses only apply on bluenile.com.
