IMHO there are a number of factors at play here:
1) Although our numbers are increasing we are still a niche market and do not represent a significant portion of the population, certainly not by the standards of major corporate marketing - they aren't interested and don't care about us.
2) Selling one puck of VDH soap and a couple of $ worth of blades every few months is of no interest to a major supermarket chain. Compared to a pack of gillette cartridges and a can of shave gel every couple of weeks it's peanuts.
3) Frankly, the rate at which new wet shavers are being recruited is probably less than the rate at which old wet shavers are dying.
4) We are too diffuse in the population to support a brick and mortar business unless it's in a major first worlld population centre like London, LA, NY, etc. Internet businesses can flourish only because they effectively aggregate business from . . . well in effect the whole world.
Very well stated.
that is a lucid, intelligent, well thought-out statement.
