Gentle makeup remover can be made in minutes for pennies. This recipe even removes waterproof mascara. In a 4-ounce container (leftover from your last purchase) add two teaspoons of oil of your choice (jojoba, grape seed, almond or olive) and two teaspoons of non-soap cleanser such as Cetaphil. Fill with water and shake. That's it. You'll have to shake it up with each application because the oil will separate. If you have more than one makeup wearer at home, this one DIY substitution saves at least $100 a year.
