While marketing your products at a farmers market is a great way to sell direct to customers and garner instant feed back about your products, it does require you work at providing customers with the best shopping and purchasing experience possible, if you want repeat business. Simply putting your products out and waiting for customers to make their selections and then pay you is the same as shopping at the supermarket. That's called transactional marketing.
Instead, provide customers with a great shopping experience anchored by high quality products and you'll become a super market vendor. This is relationship marketing where the customer experiences a value-add connection with you as the producer. This presentation examine the traits of highly successful market vendors including market organization, display techniques, signage, communications at the market and through social media, and the vital customer service techniques used by super market vendors.
