How does a factory not supply certain dealers? I'll tell you.
The amount of money the dealers are making off these forums is incredible. These forums make up a huge percentage of their sales. Andrew, being the biggest seller, has the clout to make special deals with the manufacturers.
He says to them: in return for blocking certain dealers who don't play by my rules, I will give you a bigger cut of my profits, or I will buy wathces from you at a higher price. Of course, they agree. This causes other dealers to set their prices to what Andrew demans, therefore, causing prices on the rep forums to go through the roof. The point isn't to ban all buyers in china, the point is to control the few that are called "trusted dealers" on the rep watch forum, which number about ten. Since we don't buy from those outside the "trusted dealer" network, the prices become artificially high for all of us.
In other words, he is screwing all of us behind our backs.
