Was looking around to see if any ClickFrenzy offers applied to The Ordinary and found these cashback offers. Both stores are essentially the same company, just with different websites. They both stock The Ordinary (including the foundations) and other Deciem brands, and the products seem to be the same price as on the official website. You'll get the best cashback if you're a new customer, but if you're not a new customer of either, you can get 14% cashback from R.Y. Both stores require $50 order for free shipping, or $6.95-$6.99 for orders under $50. If you are a new LookFantastic customer, use 'LFAU19' for free shipping for orders under $50.

Thanks moocher, restocked on The Ordinary :)
Code LF15 might get you an extra 15% off your order although it has brand restrictions it seems. The Ordinary was excluded from the discount.
