Instead of purchasing new cosmetic applicators wash your old ones to save money. Just wash them in warm water with anti-bacterial hand soap, let them air dry and then reuse. It is very easy to get an infection from old brushes so keep them clean and you can continue to reuse them.
This might not save you a lot of money, but a little money saved over time adds up!
