I think it would depend (at least partly) on how long the person had been collecting and such. Myself, I have been collecting for a little over a year, and, because of where I live (Australia) I have few in the way of "niche" scents. They tend to be VERY expensive and hard to get here. So, I have lots of Dior, YSL, etc. Yes, I love Miss Dior and Nu, but, partly, that is because I am just now figuring out how to sample Montales, FM, etc. so, I don't know. Where was I going?
