It's attractive enough and functional. Only issue is that when liking a window opens with "Say something about [facebook page]", but it's inside the Social Offers box. It took a minute for me to get it to stay liked and be free of the box to see the code. As it is users may get frustrated and rage-quit the whole purchase.
If it were fixed to prevent the box from appearing or have the box appear on top so that it cold be closed, it would be a 5/5.
