Becoming a distributor?

I've been doing a lot of reading on this site and others like it and it seems the way to make the most profit is to become a distributor of these products? Someone posted somewhere here, not sure where, that is what a lot of powersellers are doing? My question is how exactly does one become a distributor, i've looked on two major sites for any information (sony and nike) and cant seem to find anything. Thanks ahead for your help.

So no one can offer any help?

Many suppliers Require a min Purchase and others have what is called MAP Pricing.
It is hard to become a dist for this reason
You would have to have some Capital and perhaps even a store front
