Walmart continues to offer the Philips Sonicare Essence 1 Series Sonic Electric Toothbrush, model no. HX5911/10, for $19.97. (Amazon has it in a different color for about the same with free Prime shipping.) Choose in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from last week and the best deal now by $6. It features a contoured brush head, charger base, and 2-minute smart timer.
