I usually agree with your posts Ace, but I do disagree with the above. When a particular razor's price doubles or triples overnight it's not invisible market forces, but people stoking the market. This can be done various ways, but the most effective method is hype (combined with ignorance). Would I pay $500 for something that was $100 only a year or two ago? Certainly not, and I'm sure the people paying those prices wouldn't if they knew that too.
