Walmart offers the Oral-B 1000 CrossAction Rechargeable Toothbrush in Black or White for $32.95. This $15 mail-in rebate cuts it to $17.95. Pad your order over $35 for free shipping. (In-store pickup is also available.) That's the lowest price we could find by $5, although we saw it for $3 less two weeks ago. (For further comparison, most merchants charge $40.) It features an in-handle timer and pressure sensor. Deal ends December 31.

Update: White has dropped to $29.95 before rebate, $14.95 after.
