The great new $4 Dove Register Reward deal is rolling! What does this mean? You can currently use the $4 Dove Register Reward you earned from a previous transaction to buy another Dove Shampoo or Conditioner or Styling product and you’ll get back another $4 Register Reward. You cannot usually “roll” the same Register Reward deals, so take advantage of this while you can! I can confirm that this “rolling” works!
