MAC Cosmetics offers a MAC lipstick of your choice for free when you return six MAC primary packaging containers via post or to a MAC Cosmetics counter as part of its Back to MAC Program. That's the first such offer we've seen from MAC, yielding a savings of at least $16. (Plus, you even get to choose your preferred lipstick shade.) Eligible packaging containers include empty eyeshadow cases, lipstick tubes, powder compacts, foundation bottles, and more.
Before you send in your tax return, double-check that you haven't made one of these mistakes that can trigger IRS scrutiny.
