Yes, they have ticket purchases on their website. There is a small fee for doing so
One warning about their website. The way you select a date is really odd. On my computer, the calendar for selecting a date is hidden by the weekday name and the whole page looks funny. I have tried several computers and browsers and it always looks terrible.
You can purchase movie tickets online at galaxytheaters.com or by using their mobile app. Be aware that there is an added fee for purchasing online.
