What's the funnel before this? Is this from cold traffic ads.
Because I'm certain this is because it's really unclear on exactly what you're getting and people click "Get your $15 tickets" expecting a lot more information and just being asked to pay
Think about the questions you have when you want to go to the cinema;
What movies are on?
Where is it playing?
What time is it?
None of these are addressed so you need to be super clear that this is basically a voucher you can use at any of the given locations and for any film etc (at least that's what I assume because it's not explained - if it's in the FAQs that's too late, this is the core information people will need to convert, I'd expect, so it has to be crystal clear what they are paying for)
