I mean, if it's worth it to you to pay extra to get exactly what you want, I don't want to discourage you, and you may very well be able to sell the extra molds. I'm doing custom bar molds because I didn't find anything in the right weight range that felt special enough yet not a nightmare to polish. I'm going to focus on acquiring new wholesale accounts in the fall with the new bars in new packaging plus nutrition info, so hopefully the investment will pay off. But I don't buy those $50 chocolate molds you speak of, I much prefer $20-25 so I can get more of them, or other toys, like a large stone remnant for the kitchen that I need to figure out how to lift onto the table without breaking ... today's challenge!
