The holidays (and holiday photos) are still a ways off, but it’s never a bad time to whiten your teeth, and Amazon’s running the best Crest 3D Whitestrips we’ve ever seen for Prime Day.

Get a box of 20 treatments plus two express one-hour treatments for $28. That’s about $17 less than usual, and actually $1 less than a deal we saw over a year ago, which included two stackable coupons, and sold thousands of boxes among our readers.
