I've been in business selling M&P for about a year now, and I've never tried cold process. I know that with CP it's a lot more complex and would need months and months (or even a year) of testing recipes and what not but that's not the issue here. My question is about the cost vs. profit. I feel that the M&P mark up is really small because the soap base itself is quite pricey when your not buying bulk quantities. Is there more of a profit margin for CP? (Or are the supplies equally as expensive?)
