Kiehl's offers four deluxe samples for free on orders of $65 or more via coupon code "HEALTHYSKIN". Plus, the same coupon bags a free Ultra Facial 5-oz. Cleanser on orders of $100 or more. (This will add to your cart automatically.) Even better, all orders of $50 or more qualify for free shipping. That's the best freebie offer we've seen from Keihl's since last summer when we saw five free samples with any purchase. Coupon expires March 24.
