Less than 6 bucks is expensive? That can is bigger than you think. I've been working one can for the last 6 months.
Hard to beat natural tallow from animals. Especially cool little minks. It doesn't melt in summer, or freeze in winter. Nothing to mix. It comes as a perfect paste ready to use.
If you feel you have to do it yourself. Trap some minks, and make your own. It's my plan.
