Prime Day Ends Soon — Here's What I'm Buying Before the Deals Disappear

Crest 3D Whitestrips Sensitive ($28, originally $50)

I've tried these whitening strips before, and I really appreciate how simple they are to fit into my daily routine. Each box includes 18 treatments that lift stains gently without irritating my sensitive teeth. They're enamel-safe and deliver noticeable results, and with nearly 50 percent off, I'd definitely repurchase them. 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
