Now that the Cinemark link is up on that page I see there’s an SLC showing, ROCK ON. $20 for 3 movies is a good deal anyway; I hadn’t even thought of what tickets might run. Can’t wait…
And the babysitter just emailed to say she is free! 
Well, the OP’s link works, but none of the links on that page work! I keep clicking AMC and Regal, but a small pop-up window opens that leads nowhere.
It’s not just you. Page’s got messed up links.
