Q about free samples at purchase
I've always been curious but how are free samples selected when they are given out with a purchase at the store? I'm 23 and I often receive the most irrelevant samples (mature skin serum, wrinkle fillers, foundations that would require me to change ethnicities, etc.) and have been since I started shopping Sephora at 17. I have this giant jar filled with useless samples I never, ever use. So yeah, is it random? Whatever is being pushed at the moment?
