If you're a regular reader of Allure, it's probably safe to assume you've got a strong interest in the ever-evolving world of beauty. Products, trends, and even news — you love it all. But let's be real here: Beauty ain't free. Which is why we love calling out the best deals and steals when we find them. And today's discovery is just too good to pass up. M.A.C. is handing out free tubes of your favorite lip products.

Starting today, the cosmetics giant is offering shoppers free — allow me to repeat that — free lip products in all M.A.C. stores and online. All you have to do is buy two lip products (lipstick, lip gloss, you name it) and you'll get a third free. It's that simple.

The sales initiative, called #MACLipsLipsLips, gives M.A.C. fans a chance to scoop up all their favorite lip products from the brand in just about every formula, texture (matte, gloss, stain, etc.), and shade while still managing to snag a full-size freebie. That means you can stock up on your precious
