Bayer Migraine Printable Coupon: Up to $3 off

Sharing the Bayer Migraine Printable coupon with your friends can net you $3 off your next purchase.  You also have the option to not share, which gets you a $1 coupon.  Either tweet, Facebook share, or type in the email of 5 of your closest friends to get the higher value offer.  

I've done a little checking, and the Bayer Migraine appears to be priced around $6, making saving $3 very attractive.
