That topic has been discussed here:

We don't want to show you any information on our set up if we don't have to. We are getting plenty of business the way we are set up already. We do not want to violate our sales agreements with our supplier(s) and there are other issues which may put our entire operation and customers at risk if we were to fulfill these requests.
It's a shame, because you'd be a multi-millionaire if you did. I've shown plenty of people the pb website, but only one has signed up because of the lack of information. I've been happy to take the risk myself, but I've found it hard to convince others to put money in to this operation.
