I would definitely be trying to get out and actually do some real life sampling more than just Craigslist. People don't get a feel for the product through Craigslist. If you can setup on a street somewhere, outside of some event, or even host some sort of event somewhere and advertise the heck out of it. Gotta make a connection with people more than just through the internet.
After that, might need to drop price a bit or give some sort of incentive (read coupon) to get people to try you. Word of mouth through experience will be your best advertising if you are working purely local.
