Crest 3D White Professional Effects Whitestrips | $50 | Amazon | Clip the $10 coupon
Graphic: Chelsea Stone

Here’s a deal you can really sink your teeth into: Bring home a Crest Whitestrips Kit containing 22 treatments for just $40 when you apply the $10 coupon on Amazon — that’s about $1.82 per treatment. Included among the regular treatments is one set of 1-Hour Express strips for teeth whitening emergencies, I guess, but overall, it’s a solid price to pay for a more luminous grin.
