Can I use the movie tickets for any movie?

Typically, the movie tickets you purchase through PerkSpot are valid for any standard, 2D movie. 

Tickets are subject to a surcharge for 3D, IMAX, Dolby, or any other movies with special features. Additionally, the tickets may not be valid for movies taking place at special events such as opening night fan events, double features, marathon events, alternative content, certain foreign language titles, and special theatrical presentations. From time to time, there may also be a location surcharge at select locations. 

You may want to contact your local movie theater ahead of time to verify whether or not you will incur any surcharges.
