If you're looking for something to do this weekend, I recommend checking out Begin Again at AMC. The coupon for four free tickets to see Begin Again is valid from August 29, 2014 through September 1, 2014. The following tweet was published by @AMCindependent:
Get 4 FREE tix to #BeginAgain from 8/29 - 9/1 with this coupon! RT the news & find showtimes! http://m.amcurl.com/05nbw
I have sent a tweet to AMC to confirm that AMCindependent is a legit source of coupons, but AMC's main page does follow them. If I learn otherwise, I will update this post.
