Every Tuesday Regal Transit ( http://www.regmovies.com/theatres/theatre-folder/regal-transit-center-stadium-18-imax-910)
and AMC Maple Ridge 8 https://www.amctheatres.com/movie-theatres/buffalo/amc-maple-ridge-8 have discount movie night,
the trick is; you’ll need to buy your ticket ahead of time in person on location at AMC (for AMC theater)- not online so you could get closed out of your movie of choice
the second trick… download the Regal Theaters app even if you have the rewards card- they’ll send you monthly coupons and other Tuesday night deals on things like POPCORN!
oh, and of course AMC has one too if you didn’t already know… https://www.amctheatres.com/mobile/app
