Marketing by Giving

If you are going to spend money advertising, why not give some of that money to a good cause?

You can sponsor a local charitable event by offer you product as a prize in a blind auction or open up your place of business to hold an event.

Online you can become a sponsor click-to-donate sponsor as mentioned by Marketing Power.

Either way you are attaching your company to a positive image, introducing your company to new faces and helping out a good cause while you are at it!
