Waterpik Aquarius Water Flosser, $49 after $10 coupon

Waterpik is an easier (and they would argue more effective) way to “floss” between your teeth, and Amazon is once again offering the popular Aquarius model for $49 after you clip the $10 coupon. That’s one of the best prices we’ve seen, so it’s a great time to take the plunge. Your teeth will thank you.
