Other than archerfire, what are the other sources for your decants? (i tried searching, but couldn't find)
Another, newer one http://www.checkitoutone.com/ . Also, if you do a search in this section on samples, there should be a page with a number of other sources including Luckyscent and Aedes. Also you could go to department stores and fragrance shops to sniff there. Might help to know what fragrances you are looking for. Some of the manufacturers do offer samplers of products including scents; G F Trumper comes to mind.
