MY COMMENTARY:
I think this is less about consumer learning and more about consumer sales. With SKU reductions, payment on scan, more private label, and other plans of traditional retailers that will limit the effectiveness and efficiencies of national brands, P&G appears to be testing the waters for offering its own company store.
The pendulum has swung in the favor of retailers over manufacturers. P&G's efforts in this area are meant to balance the pendulum and insure that the company understands the opportunities/threats/challenges that online shopping creates. I view this as a terrific preemptive move.
