Saw an ad for free beer on facebook
Put in your name and phone number and they send you a text with the beer coupon which you can redeem in venue.
I repeat, DO NOT REDEEM UNTIL YOU'RE IN THE BAR. I stupidly redeemed it figuring things out.
You can find the venues when you click the link, just don't click the venue as it will prompt you to redeem.
