This company is a scam. They offer custom-blended fragrances to match any scent you can name. After-the-fact research suggests that matching a fragrance from a sample is more along the lines of chemistry, requiring thousands of dollars worth of equipment and time, and therefore not something easily delivered at a $79 price tag. Wish I had seen this in advance...
Based on my experience and what I have seen posted online, your transaction with them will go something like this:
You place your order, naming your fragrance. They do not request a sample of a rare or discontinued fragrance. You do not recieve an item in the mail and follow up; after several weeks of stalling, you recieve a perfume bottle in the mail, filled with a fragrance that's not even close to what you requested. You then ask for a refund or a replacement. Sometimes they will tell you you're past the 30-day window for money back guarantee (even if the item didn't even ship for 45 days); sometimes they agree to retry, requesting "a few drops" of a sample. That's what happened with me. I sent them a "tester" size of the perfume I wanted matched (which by the way isn't made any more so that tester was about a third of what I still have) at my own expense, returning their first attempt. Then email silence for about 4 weeks; they would not even acknowledge reciept of the return. Only after threatening them with reversing the credit card charge would they acknowledge they were "still working on it." Several weeks and several unreplied emails later, I asked the credit card company to open an investigation, which is when I started getting some pretty unfriendly emails from Scentmatchers.
There's a good chance, if you do business with this company, that you'll end up having your credit card company reverse the charges.
