September means "back to school "
for students who frequent your location.
And it's the time for you to plan your
"curriculum" of school promotions.
Advertise your locatiof'il in local school
newspapers, including a cuwpon good for
a free ~ame. Or. advertise that players
who bring 1n their ticket stub following a
school football game or other event will
receive a free token. Set up a program
of awarding game tokens for each "A"
or "B" on your players' report cards. Of-
fer to loan games to your local school for
a special student function or fundraiser.
Or, offer to speak to a business class
about setting up and operating a location
or route business.
There are dozens of ways to promote
your business by becoming involved with
your local schools. It will not only encour-
age hundreds of potential players to visit
your l~c~tion, but can improve your im-
age w1th1n the community as well.
