If you typically hate surprises, we have news that’s bound to make you feel otherwise. Starting this Sunday, April 28, L'Oréal Paris and Maybelline New York have teamed up to launch a special “mystery offer,” happening in-store at your local Walgreens. With the purchase of any two L'Oréal Paris or Maybelline eye products, you’ll receive a mystery coupon at checkout to use for your next purchase. That means you can get up to $10 off — which, all drugstore makeup enthusiasts know, is a major discount. As for the products you should stock up on from the sale, let us recommend a few that we always have on backup.L'Oréal ParisFor starters, L'Oréal Paris Voluminous Lash Paradise Mascara is a must, especially if you’re looking for volume and drama. It works just as well as that luxe formula you’ve been scoping out at Sephora — you know the one. For a shimmery, soft, brightening eye makeup, look no further than the Paradise Enchanted Eyeshadow Palette, which will last you through the entire season. Finally, change up your traditional black liquid liner with Voluminous Lash Paradise Liquid Eyeliner in Rose Gold. Maybelline New YorkGet excited about summer with a pop of colored shadow from the Maybelline Soda Pop Eyeshadow Palette. It’s celebrity makeup artist-approved and has everything you need to create a simple everyday look to a dark, smoky evening one. Pair it with the classic Volum' Express The Falsies Washable Mascara for serious volume and complete your eye look with the TattooStudio Waterproof Eyeliner Pencil in the shade of your choice (we currently can’t get enough of Striking Navy).  The Mystery Offer promotion runs from April 28 through June 29, which is a generous amount of time to stock up on drugstore must-haves. So get shopping, and may the beauty odds be ever in your favor!Read More:Here’s Why You Need a New Foundation in the SpringThe Essie Glazed Days Collection Is Here — Check Out All Six Bright ShadesUpdate Your Beauty Basics for Spring
