Drop the price of the Oral-B Professional Care SmartSeries 4000 Rechargeable Power Toothbrush from $99 to $39.99 and get a $50 Restaurant.com gift card code by checking the boxes on the Drugstore.com page under "special offers." Scroll down, and you will see it highlighted in gray, with the words "Just $39.99 for Oral-B 4000 when you click this link!" and "Get a $50 Restaurant.com gift code with select purchase!". Check the boxes next to both offers before you add it to your cart. Even without the gift card, this is the best deal for this best selling toothbrush by $54, and a new all time low by $5! This may not last, so act fast. There is no sales tax (except IL, NJ, NY and WA).
