Every time I go to the dentist for a cleaning, he both compliments me on the excellent state of my teeth and tries to sell me an overpriced sonic toothbrush. Um. Thanks? But no thanks. Why would I buy a supposed top-of-the-line model (complete with the dentist’s mark-up!) when I could get something like this highly-rated Oral-B Vitality Floss Action Rechargeable toothbrush, instead, for under $15? It’s currently marked down to $19.96 and there’s an available $5 coupon to clip. (You can also snag this 3-pack of replacement heads with an available $3 coupon to clip, and if you buy via Subscribe & Save you could end up paying as little as about $11 for ’em.)
At this price, it’s a no-brainer. And based on the reviews, I don’t think you’re getting an additional $100+ of “extra” on a more expensive model. But hey, if you want to spend more, I certainly can’t stop you.
[Edited to add: One coupon use per account. If you have two kids, like I do, text your spouse “please go clip this coupon and buy one of these.” Mine didn’t even ask why, which is a sign of a perfect marriage, obviously.]
