Graphic: Shep McAllister

Even if you diligently brush twice a day and floss every night, your teeth might not be as white as you’d like. Crest’s 3D Whitestrips really do get the job done though, and you can grab a box with seven 1-hour express treatments for $26 today, the best price Amazon’s ever listed (though we have seen better overall deals with coupons).
