Recycle...and get a lipstick

Have you been eyeing a certain MAC lipstick color? Don't throw your empty containers away! Once you have six empty MAC containers, they will repay you with a free lipstick. Just go to a MAC counter or fill out the form to return them online, it's that simple. Sweet deal, right? Even more reasons to keep buying from MAC. I contacted MAC to inquire about which lipsticks are gluten free, and they said to the best of their knowledge (which may not be 100% due to ongoing changes and different suppliers) the following lipsticks contain these ingredients:

"Lipstick (Amplified Crème) - contains barley extract, wheat germ extract and soybean extract
Lipstick (Cremesheen) - May contain ingredients derived from Wheat, Soy and Corn
Lipstick (Dazzle) - Contains ingredients derived from Soy
Lipstick (Frost) - Contains ingredients derived from Corn
Lipstick (Glaze) - Contains ingredients derived from Corn
Lipstick (Lustre) - Ingredients derived from Corn and Soy
Lipstick (Luxe) - Ingredients derived from Soy and Corn
Lipstick (Matte) - Ingredients derived from Corn
Lipstick (Mattene) - Contains ingredients derived from Soy and Corn
Lipstick (Satin) -Ingredients derived from Corn and Soy
