Amazon has a coupon for $7 off an Oral-B rechargeable product. Click here and add a Oral-B product which costs less than $7 such as this and clip the coupon = FREE!
Note: This item is part of the new Add-on program where items only ship on an order of $25+. If you are not purchasing anything else at Amazon and would still like the FREE toothbrush, you can place an order for $25+ by adding other items, you can then cancel the extra items, the rest of the order i.e the toothbrush will still stay part of the order and ship!
