I buy it from Amazon and it is much cheaper than Target or Walmart.
You get 3 Pro-x items in a kit: Under eye moisturizer for day and night, a morning moisturizer w/ 15 SPF (I use this under my makeup or by itself) and a night moisturizer.
I have sensitive skin and acne prone skin and this work great for me. I put it on auto-renewal at Amazon. In the beginning I got it every month, now I get it every 2 months. I have found that I go through the night moisturizer quicker than the other 2 items.
