Note: I’ve edited this post to update it now that Nancy has her own site.
Nancy at Fishbone Fragrances is carrying samples and 5 ml decants of many Sonoma Scent Studio fragrances. This option is a nice way to sample if you’re already ordering there, especially if you are overseas and trying to combine sample orders to save on shipping. Nancy has fabulous customer service and a great selection of fragrances. You can visit her here (she’ll be up and running within a few days):
