Samples ship free. If you’re ordering samples only, please choose at least four. If you’re purchasing another product, you can order fewer than four samples. One of the most challenging things about buying perfume online is that there is no way for you to try for yourself before you invest. These sample offerings are our way of addressing the issue of uncertainty. Trying before you buy, having confidence that your purchase is actually what you want is the only way to solve this dilemma. These samples are in 1 ml vials, filled about 1/2-3/4 of the way full (more or less). This gives you enough of the oil to wear it a few times and see for yourself if it's a good match for your own personal chemistry. Thanks so much for your interest.
