Wow... good insight from Maury Kosh. Some principles could apply to my art print sales. I have known many soap makers and other fun craft makers that sell at monthly ( some weekend) markets. Gruene Market Days is in New Braunfels, a long drive but a great monthly market. I have been wanting to try the weekly market in Grapevine, TX.... a lot closer. A crafts market usually draws people who like hand crafted soaps. I know this is not a direct answer to your question but it s another idea. I love helping arts & crafters.

Let me add: people are more likely to buy and item when they have fun meeting the crafts person or artist and a periodic market puts subtle pressure to 'buy it when you can'.
