Dude. It's 2019, undercutting my price in a market with asymmetric information isn't how business is done. We are both the only people who know. We're already breaking the law by disclosing, so we combine information and price fix. $15 for our knowledge, we split profit 50/50 and walk away with more money and less competition than we would have had otherwise.
Just PM me what you know and I'll verify its what I know.
