So is Gillette only able to successfully sell large quantities of its expensive, flagship Fusion razors and refill cartridges when their price is subsidized with promotional support (ie, on sale)? I had read a year or two ago that Fusion hadn't been the home run that Gillette had hoped, partially due to its high price in the face of the great recession. In response, Gillette was changing its marketing to assert that the Fusion will give X number of shaves and as a result is a good value.
It's called drop-ticket marketing.
Make something that costs you $0.50, make the MSRP $5.00 and sell it based on that, sell it for $2.50 and make a killing.
