I read that woman's post, too, about 18 tubes of toothpaste. I'm sure she re-submitted info saying that she wasn't going to use them all for herself. The benefit of getting so many so cheaply was that she planned on donating them to a charity/homeless shelter or something.
I've acquired only as many as, say, 6 antiperspirants and 6 body washes. One caution, however, since I stopped using the body washes with the puffs in the shower for some time (maybe 3 years) the oil in the body wash turned to a rancid smell. So much for the perfumey aspect of them! They still clean me as well (I'm back using them) - but I have to put more body lotion on after my shower, just in case the rancid smell remains. Anything with oil, like, of course, cooking oil or even hand lotion can go bad and smell rancid.
