Sephora has several great offers for several items you can recieve free when you order something, download their app, or make a purchase over $16, or $25.
QualityHealth.com is offering a free winter sample for signing up for their free health newsletter, the free sample includes Chapstick, Nivea, and Lubriderm Products.
My favorite mineral makeup, Everyday Minerals always offers free samples of their makeup, just pay shipping (I believe it's around $3) and you'll recieve several shades of foundation, blush, finishing veils, etc. of your choice! They also run a new promo every week. This week, receive a free Any Time Any Place Lippie and Bollywood Blush in mini-size on all orders over $25.00.
