Use this link, type any word in the yellow blank spot (I typed food, cats, music, friends, etc and got a lot of offers). You have to scroll your mouse over the pics to find the Facebook offers. I have 4 waiting for me in my email. It allowed duplicate offers to the same email address.
So far I've found offers for buy one get one free entree and free chips and queso with any entree.
It says you need to connect to Facebook to get the coupons. I allowed the app but chose to share with "only me" to avoid spamming my friends.
Edit: I've added screenshots of both coupons for those having trouble. All I did was show the coupon on my phone or of course you could print it out. It's not unique.
