Walmart offers the Oral-B Pro 1000 Electric Toothbrush, model no. 69055859636, for $29.99. This $15 mail-in rebate cuts it to $14.99. Opt for Site-to-Store pickup to dodge the $4.97 shipping charge. That's $21 under our mention from a year ago and the lowest price we've seen. (It's also a current price low for a shipped toothbrush by $18.) It includes a handle, Precision Clean brush head, and charger base. Rebate expires December 15.
