For its Beauty Insiders members only, Sephora takes 10% off sitewide, including sale items, via coupon code "YAYINSIDER" as part of its Spring Bonus Event. (Not a member? It's free to sign up.) Better yet, you'll bag three samples for free with every order. (Choose from a selection of 12 during checkout.) Shipping adds $5.95, but orders of $50 or more qualify for free shipping.
