so you puts a sign in your window....people get out their cell phones
and call the number in my case (410) 981-9256

they receive a recording.....then a recorded message....

go to grandcentral.com
and find out how to get your free number....it also gets you a voice
mail box and have people call you from a web page.

Works great....

I have applied for extra numbers one for each car...

this service has a waiting period but I think there are others that you
can use.

I found about this one which is free via blogspot where it was one of
the companies I think several that were recommended.

What a great way to answer those pressing questions and keep in touch
with your audience.
