Amazon offers the Philips Sonicare E-Series Replacement Brush Head 2-Pack, model no. HX7022/64, for $24.95. Clip the $7 off coupon on the product page and add it to your cart via "Subscribe & Save" to drop the total price to $16.70. With free shipping, that's $4 under our mention from four weeks ago and the lowest total price we could find by $6. They feature angled necks and "reminder bristles" that fade when in need of replacement.
Note: Be sure to cancel Subscribe & Save after your order ships or you'll be billed for subsequent shipments.
Amazon cuts up to 37% off a selection of Philips Sonicare Toothbrush Heads. Plus, clip the $7 off coupon and add to your cart via Subscribe & Save to cut prices to as low as $11 with free shipping. That's the second-best deal we've seen on Philips Sonicare items at Amazon, and yields several price lows. (We mentioned a coupon deal for $4 or $10 off toothbrushes and replacement heads in June.)
