Walgreens offers the Waterpik Classic Water Flosser, model no. WP-100, for $46.99. Coupon code "LEAF15" cuts the price to $39.94. With free shipping, that's $7 below what you'd pay at your local Target, although we saw it for $7 less last October. It features a water tank, six tips, 10 pressure settings, and tongue cleaner tip.
