Walmart offers the Philips Sonicare Essence Sonic Electric Toothbrush, model no. HX5911/01, for $19.97. (Amazon and Newegg have it for the same price.) Choose in-store pickup to avoid the $5.97 shipping fee. That's $5 under our mention from November (which included a $5 Walmart gift card) and the lowest price we've seen. (It's also the best deal we could find today by $10.) It features a contoured brush head, charger base, and 2-minute smart timer.
