Hi there!
There's a problem with VIP Events. Some days ago, a little ship came to harbour and took SP K (9 kk). The price of Sp K at drug dealer was 78 and the price at docks was 80 (only 2 dollars profit). So the max. profit was 18 kk $.
Today, it comes a little ship and took weed (109 kk) at price 9 $ (at drug dealer, the price was 7). So the final profit was over 200 kk (which is ok).

When any ship comes at docks, the price should be 15-20% bigger than drug dealer, at least this is what i knew.
