Can i money back if i return a ticket i got with a promo code?

I got a 10 dollars promo code from movietickets.com nd I used it for a
movie that was 10 dollars so I ended up paying 1 dollar (
movietickets.com fee) nd I was wondering if I return my ticket can I
get the 10 or 11 dollars back in cash/credit or what happens to the
promo code?
