Have you ever heard of Smiley360?
When you sign up you create a personal profile and wait for missions in your account. I was able to receive many samples/coupons for free by being a member. My latest mission was the Holiday Fragrances by COTY Mission where I was able to receive $5 of $30 coupon for any of the following scents shown in the photo. Smiley360 “scent” me free samples in the mail and I was able to decide which was my favorite for myself, family or friend. The Vera Wang Embrace was my favorite scent. Later, I will post all samples I have received since joining. It’s free to join and all you need to do is complete your missions and very short surveys to be qualified for more missions that are fitting according to your answers. Look forward to my next mission!
