This is one of my biggest hobbies (kind of sad, yeah?). But I love free things, and I love getting mail, so it’s fun for me. Unlike the author of this article, I don’t bother requesting baby samples or anything else I can’t really use.
There aren’t as many good free samples out there as there were 4 years ago when I first moved to the US - back then I didn’t have to buy deodorant or shampoo for a year. Still, lots to grab.
