The listing, Pair of Cinemark Movie Guest Passes has ended.
These are two guest passes that are good for any regular show (no Imax or special showings). They have no expiration date and are good for any Cinemark theater in the US. You present the passes, and then they will issue regular tickets instantaneously. These were won in a Cinemark contest. They ran out of the regular tickets to give the winners so they issued some regular ones and some of these. They said these were better because they had no expiration dates and will never expire, unlike the other ones. I think the others were prettier, though; these are just regular paper passes. I put the ones with an exp. date on Listia a year or two ago; these I've had laying around so it's time to do something with them.
