Personally, I don’t get it.
Yes, if it’s some product I’m interested in and would like to taste before purchasing a month’s supply, okay, but to load up simply because it’s free?
Pffft... Know what? I can afford to buy my own food without resorting to some impulse of hoarding gibmedats because it’s “free”.
I never take samples of food....regardless of what it is and where it is. I will cut a huge swath around them to avoid them. Just me.
