Crest 3D Whitestrips Sensitive At-Home Teeth Whitening Kit ($28, originally $50)

I've used these whitening strips countless time before, and I love how easy they are to work into my routine. Each pack comes with 18 treatments that gently remove stains without causing irritation — even on my sensitive teeth. They're enamel-safe, effective, and at nearly 50 percent off, they're a deal I'd grab again. Read our Crest Whitestrips review for more.

Editor Quote: "After just four treatments, the difference is already remarkable. The 'before' image on the left and the 'after' image on the right clearly show the noticeable change. And I've barely made a dent in the box, with plenty of treatments left." — Marisa Petrarca, contributing shopping editor
