Circuit City via eBay offers the Wellness High Powered Sonic Electric Rechargeable Toothbrush for $17.99 with free shipping. That's $2 under our February mention and the lowest price we've seen. (It's the best deal today by $7.) It features three modes and includes 10 brush heads with a holder. Note: Coupon code "PERFECT3" cuts that price to $14.99, however this coupon is intended for first time purchases on eBay. It can only be used once per account.
Reviewing this critical insurance policy takes a little effort, but it pays off big.
