Emily,
I love Mary Kay. If price is an issue for you, and you love the product, you know that your consultant can have you host a party, and you can win free product? It sounds like you have bought MK in the past, and most likely have a consultant already. I would ask her about ways to win those free products that you love. I have been down the drugstore route, and you just end up spending more money over time trying to find something that works.
