Walmart offers the Oral-B 1000 CrossAction Rechargeable Toothbrush in White for $39.97. This $15 mail-in rebate cuts it to $24.97. With free shipping, that's $5 under last month's mention and the lowest price we've seen this year. (It's the best deal today by $15.) It features an in-handle timer and pressure sensor. Deal ends December 31.
