Sounds like my grandmother Mar...
She was renowned for her old-fashioned layer cakes, Blackberry Jam, Carrot, German Chocolate, Red Velvet, etc. She would bake them to donate for charity raffles and then people started asking her to make and sell them. She was flattered, and Ohmigosh, she charged a whopping $7 for these cakes (this was the 70-80's). I kept telling her she needed to raise the price (you can imagine how many cake requests she was getting at that price). I finally totaled up all her ingredients and showed her she was going in the hole on each one. She raised it to $10 (to break even). Grandma, grandma, grandma, that's not how it works. She nearly had the vapors and fainted when I suggested a starting price of $25.
