Estee Lauder - Free Foundation Sample (via FaceBook)
I clicked on the link but for some reason it keeps taking me to their website.. so, here's the correct link: https://www.facebook.com/EsteeLauderAustralia/app_302317369838113
You will receive a sample voucher, which you take to your nearest David Jones Estee Lauder counter to redeem.
To access it, 1) Like their page on Facebook 2) click on 'Try It Now', 3) click on 'Go to App', 4) click on 'Love it' 5) select any drop down option and 6)'Try a new makeup you will love'. And you will find the registration form for the sample. (It is much easier than it sounds)
