I just got wind of a free offer from Heineken. Fill out a brief three question survey (have you ever tried Heineken? Do you know it's available in 193 countries?, etc), put in your mobile number, and voila! You'll receive a code redeemable at your local pub.
Get started by clicking this link.
Disclaimer: I'm passing this on to you because I like you. I don't receive anything from Heineken for posting this, but like my page/retweet this to show your gratefulness!
