Well, imo, if someone wants you to do an open house and wants to buy, there's really no question, other than yes, do it or no, don't do it. If you give stuff away now, or sell it cheap, you'll never convince those people to buy once you've changed your mind or business plan. It's no different than craft shows. Committing to a full-fledged business shouldn't be part of the question. It's a 1-time event. Do the open house, tell everybody you know to come and bring a friend, have a little contest for a freebie (guess the scent, or something fun and easy), but sell everything else at your cost x 2 or 3, and have fun. It's an easy way to recoup your costs and gives you money to move forward.
