Yeah, only problem with AliX is that most of their products have to be bought in pretty serious quantities - generally 100s if not thousands of pieces per order. As I stated Ebay, Etsy, Mini in the Box, etc are all better and easier for this sort of thing.
I have never bought more than three items on aliexpress.com and all my soap stuff is from there. There is a search button "one piece" and it gives you the single item listings. Also if you ask the supplier, most of the time they will send you one piece.
