Short answer, you don't. Desert Essence jojoba is the best deal around. Many grocery stores or co-ops have it at 4oz for $8-$9. Most beard specific oils are going to be between $15 and $30 per oz. balms vary in price even more, but I have found that mans face stuff balm is pretty affordable at $20 for a 4 oz tin. They have an etsy site where they sell their products
