The offer has expired. Atom Tickets is a relatively new movie ticketing service. (It was launched in the last year or so. They’re unique because you can also pre-pay for concessions.) They’ve been offering lots of promos and deals. Its latest discount is a buy-one-get-one FREE ticket for The Wall (starring Aaron Taylor-Johnson and John Cena.) The discount automatically appears in your account, when you add two tickets to your cart for the same showing. Of course, a small service fee applies, but it’s still a great deal. I have seen the psychological thriller and it’s short at 81 minutes, but really good (lots of suspense.) To get the deal, click here. There is no mention of an end date for the promo, but I would assume it will only last for a few days.
