I've both bought AcneFree in stores and ordered on the website, and I highly prefer the website. After a couple orders I've started receiving random free product! I don't believe it was a mistake because it's happened twice (retinoid X2, second time also included a small sunscreen). I was elated, because I am very, very broke but need AcneFree because acne is a medical condition, and it also helps my mild psoriasis. The retinoid goes fast, so that's especially awesome! I'm sure it's a free sample type deal, like Sephora has, but it was totally unexpected and even though I'm not expecting it every time, I'm very grateful!
