When you purchase something from Sephora.com, you are allowed to pick 3 samples. Most samples I can't use because they are perfume (which I am allergic to) or have oil in them (which will make my skin break out). I would really like to see Sephora have samples of perhaps eyeshadow pigments or lipstick/ lipgloss/ lip-balm.
Better sample selection has been a continuing request on here. Most times just about all the samples are fragrance or some kind of foundation or item that would hardly match anyone's skin. Maybe if enough people agree with your post, Sephora will change the samples!
