C'mon, this HAS to be a joke, right?!
VaevTissue is marketing USED tissues to help you fight a cold or the flu..
From their website: "We believe using a tissue that carries a human sneeze is safer than needles or pills."
Alas though, that same website also claims they are completely sold out of the tissues. So, guess you'll have to ask someone you know if you can have theirs?!
