After my most recent trip to MAC to stock up on some goodies, I was asked by the associate, "Are you familiar with our recycling program?" And I was definitely not up on this very environmentally (and wallet!) friendly endeavor!
my everday M.A.C. go to products: brow set and brow liner
According to the MAC website, "because we share your commitment to the environment, MAC accepts returns of its primary packaging through the Back-to-MAC Program. By returning six  MAC primary packaging containers to a MAC counter or MAC Cosmetics online, you’ll receive a free MAC lipstick of your choice as our thanks to you." You can check out all the details of the program here.
RECAP: Return 6 empty containers of any MAC product and receive a lipstick of your choice for free :D
So let me get this straight...you get to help the environment AND receive free makeup for doing so?! Sign me up! Only wish I had known this sooner...I'd be up to a few lipsticks by now!
Live for luxury? No trust fund, no problem!
Join the fancy free journey as we seek the
finer things in life, sans millions.
