My field sells paint in the pro shop at a normal msrp for people with their own equipment, compared to a higher Mark up for the rental packages. If you buy a gun there its free service on it.
If you give them an email you get 50 balls free.
The biggest incentives are free passes to waive field fee. Still have to buy paint.
