Suppose the world changed and in that hyperspace moment of change, you found it impossible to get any more customers, new people to "try" your product and new league bowlers to replace the dropouts

What would you do and how would you do it?

Create a referral program that encourages existing customers to bring new friends. Constantly build campaigns (every month)that target existing customers.

Segment your existing customers by frequency of use and build programs to increase usage from low usage to medium usage to higher usage.

Provide rewards to people for learning to bowl and improving their average so they will gain a sense of achievement and willingness to continue to bowl.

Establish an existing bowlers "insiders club" that offers members exclusive offers as it pertains to bowling, restaurants and travel savings.

Maybe you should market your business that way now?
