lol... Competing over a single customer? These guys aren't official "dealers" are they? Anyway, explain the truth to each of them and then only buy from the one who offers you the best deal long term. Then try and be friends with the other three by just smoking WITH them, matching bowls and shit. But remember: stick to the one who offered you the best deal long term. I would imagine at some point the other three will be able to offer cheaper prices. If friends are more important then money to you, stick to one dealer. Make him your DEALER and the others your friends. It's also cool to be friends with your dealer. If money's more important, buy from whoevers cheapest with the best herb whenever.
