Looking for a legit way to farm coupons?

Get a silenced weapon. Go to Cordon Rookie Village, just to the west is the army central checkpoint, there is another smaller checkpoint near it . Patrols spawn there pretty regularly. Can farm aks / ammo / pistols for cash and sell it back at the rookie camp.

All these people looking for ways to use bugs etc etc. Gotta do it the original stalker way!
