We see something up ahead in the road. We don't quite know what it is but something is definitely happening. We slow down. It's human nature to look at the unusual. I can tell you, a few balloons, a couple of strings of colored pennants and some merchandise out on the street will attract attention.
Schools always have fund raisers of some kind going on.
Maybe they would like to sell hot dogs or sodas at your grand opening. Don't buy the sodas or hot dogs for them, they can probably get them donated by one of the local food stores. If school age customers are your market, this is even more effective. If you need an older crowd, offer the same deal to Kiwanis, Lions, Elks, VFW or whoever needs help in your community. You help the service club and promote your business at the same time.
