Walmart offers the Philips Sonicare Essence e5300 Rechargeable Power Toothbrush, model no. HX5351/46, for $37.99. This $10 mail-in rebate cuts it to $27.97. Opt for free Site-to-Store pickup to avoid the $5.97 shipping. That's $9 under the lowest total price we could find for this item shipped (outside the price below), although we saw it for $8 less shipped three weeks ago. Sales tax is added where applicable. It features a 2-minute brushing timer, battery charge status light and audible reminder, brush head holder, one contoured brush head, and more.

Of note, Drugstore.com has it for $29.99 with free shipping via the rebate above.
