Parfums Raffy, an online sales outlet for discount designer fragrances and a few (non-discounted) niche fragrance lines (read Montale) also offers their services in blending customized perfumes. Unlike some other companies that make "custom perfumes" for low prices (such as Garden Botanika), which only allow you choose a one note in each category (top, heart, base) and that's all of your input, Parfums Raffy just offers a list of notes from which you select your favorites and then you even get to decide which notes to have in higher concentrations. You can choose from a list of about 90 singular notes to choose from and you can also order samples of any of the notes for $1 each if you wish to experiment with your blend before ordering. Once you have decided to order, just follow the instructions on the website and your 1.7 oz bottle costing $39 will be mailed to your home. I haven't tried it yet but I definitely will be.
