Walmart offers the Oral-B Professional Care 1000 Electric Toothbrush for $26. (Add to cart to see the price.) Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. That's tied with last week's mention and the lowest price we could find by $14. This toothbrush features a pressure sensor (to signal when you're brushing too hard), 2-minute timer, and charging base station.
