Erin's tallow business

Does anyone really believe her tallow business is supporting her family? Her tallow sells for $38. Let's be generous and say her expenses are 13 per jar (its likely a lot more). Her rent is 2500 so she will need to sell 100 jars of tallow monthly just to pay rent without any other expenses. She s better off selling meal planning kit with menus and recipes. Much less overhead for her. Also Chad needs a real job.
