Let’s say you’ve already upgraded to a good toothbrush; what’s the next step for cleaner teeth? Judging by the user reviews, this 20-count box of Crest 3D Whitestrips is a great place to start. As an added bonus, you’ll even get a pair of express one-hour treatments, so you can see some improvement in time for holiday photos.

Any price below $40 for this box is a solid deal, and $30 is one of the best deals we’ve seen.
