Black Market missile sales!
The seller puts missiles out at a price, but there's a chance that the missiles get intercepted by the International Ballistic Missile Agency and you get nothing. Prices +/- 10% of each other are averaged if a sale is made.
The buyer states a price they're willing to buy at, but the IBMA may find out and seize the assets from the intermediary. If a seller is selling for +/- 10% of the price that the buyer wants, then a sale is made on the average of the two prices (unless the IBMA intercepts the buyer's money).
Bonus points to the developers if they add a spy op to let countries know what price points to buy or sell missiles from.
