You and your neighboring businesses work together to create an event that attracts people from far and wide. Those people are amazed by all there is for them to do and see at this event.
You gain new customers that come over from the other businesses and they gain some from you. Most of all the community vibe is infectious. You lose track of how many times you hear “When is the next event?”
That my friend is a win/win/win:
Collaboration marketing at its finest baby!
