Fantastic Freebies! Hypoallergenic pillowcase
You have to love the big pharmaceutical companies.
OK, maybe you don't. But you can still fill out a quick survey for Xyzal and get a free hypoallergenic pillowcase mailed to you. If you want, they'll also email you information about their product from time to time -- I would recommend checking the box saying that you don't want any more mass-emails than you already have.
Either way, the pillowcase is yours to keep. A free product that might help you sleep better? That's pretty sweet!
