This is the very same kind of word-of-mouth I engage in to catch customers. I can't afford inauguration and anniversary parties, especially considering I don't own a physical space. My thrift shop is only performed door-to-door and the same happens with my languages and music lessons (out of my online students, when i have).The best method you mentioned here, I personally see success of my nearby shop, I barber came Infront of my shop. He started promoting his business just only verbally and his community people are started rushing towards his shop. While my online and offline both marketing is failed Infront of him, he is now successful in his business.
