So I'm a 24 Faubourg devotee, but every now and then I get tired of wearing the same perfume everyday. Occasionally I like to mix Ambre Narguile and Osmanthe Yunnan from a few sample vials I have. I was thinking about getting the dicovery/travel set with the four scents. The only problem is, the other scents really don't work on me. Is it possible to get two of each in the set? Or can you only get either four of the same or four different scents?
