I think this is from the Allure summer give way But I dont see a free item just says I get a 20.00 off

OR… For the same period, receive $20 off any in-store or online purchase of LIFTLAB skin care from an authorized LIFTLAB retailer. Please see our list of stores on www.theliftlab.com. Just type in the special code ” at checkout on our partner retailer’s e-commerce website OR print out this email and walk it into a LIFTLAB partner retail store near you!

But at the bottom it says this “You are receiving this e-mail because you are a winner of the new LIFTLAB PURIFY & CLARIFY™ Daily Cleanser & Detox Mask from the FREE STUFF giveaway in the June issue of Allure.” so I guess I won something free??
