Walmart offers the Oral-B Vitality FlossAction Rechargeable Electric Toothbrush for $18.97. Choose in-store pickup to dodge the $5.99 shipping fee. That's the best deal we could find today by a buck (although most retailers charge $28 or more) and tied with last week's mention as one of the lowest prices we've seen for an Oral-B rechargeable toothbrush. It features a replacement brush head and automatic 2-minute timer.
Some chains have retired their senior discounts. But these grocers still have deals for the silver-haired set.
