“Food in Mouth” Advertising
To attract more quality oriented patrons, look for worthy local charity events and offer to feed their volunteers for free. Typical groups include firefighters, the local SPCA, Rainbow Society, etc. Ask event organizers for a count of volunteers and provide that many “personal pizza” gift certificates.
In addition to building goodwill, this an effective “non price” way to get potential patrons to taste your pies for the first time. As a result, many will eventually become loyal repeat customers!
