The theory posed in another thread in this forum about the same commercial is that Fusion sales are stuck regardless of how much advertising money is thrown at them. Just a sign of how customers in a tough economy are reacting to the outrageous prices (and profit margins) for Fusions.
That said, a Kroger nearby is clearing out their house brand of cartridges for the Sensor made by Personna for $2.39 a 5-pack. Since the summer of gentlemanly restraint is over and I had an old Sensor handle lying around, I couldn't resist, for the sake of science and experimentation.
