I save money on cosmetics at costco. They have a line of mineral and other makeup fairly affordable. and often the packages include double the amount at half the price. For example I bought mineral foundation for $20,That including the kabuki brush and two(versus one) container of powder foundation.
Most of their makeup/moisterizers etc are this way. The makeup is just as good if not better than bare minerals and the makeup is made by Borgessi with costcos name on the label!
