Got allergies? My doctor recommends all of those hypoallergenic mattress and pillow covers, because supposedly they keep the mites from infecting your bedding.
(Now there’s a cozy thought for the morning, hmmm? Dust mites! Living in your bed!)
Anyway, a rich drug company wants to give you a free pillowcase just for filling out their survey. Consider it doing your part. Or just getting free stuff. Whichever.
