On Saturday, July 29, M.A.C. Cosmetics will be giving away free lipsticks, in honor of National Lipstick Day.

To snag the (fully-sized!) freebie, just head to a M.A.C. store or retailer on the date. There's no catch and no fine lines.

Mark your calendar, set a reminder in your phone, do what you have to do. Be warned, though, the lines are sure to be long and once the free lipsticks run out, that's it.
