Our favorite smart electric toothbrush is cheaper than ever in an early Amazon Black

We're still a few weeks away from Black Friday, but if you're looking to get a new electric toothbrush, you can get a deal on one of Oral-B's models as early as today. The Oral-B iO Series 7 electric toothbrush that comes with two brush heads is currently on sale at Amazon for $150, which is a record low for the device that typically sells for $200. Even better, you can get it for $140 if you apply the website's $10 coupon, so don't forget to tick that little box right next to it.
