La Mer Cosmetics (Brand New)

I got the a few La Mer cosmetics as a gift but it’s not the right type for me so I’m going to sell it for over 60% off retail price. I took the cosmetics to La Mer at HR and got confirmation of its authenticity. However I was told these were products that were discontinued. She said it’s still unopened so it’s ok to use.
