I buy regal movie tix from Costco sometimes. Is the ticket worth the same for every show or does it have more value on RPX screen or night shows as opposed to matinees?

Special screenings, such as RPX and 3D cost additional. The tickets should cover the cost of regular screenings and matinee's.

Remember the matinees usually cost less so technically you are getting less for that ticket. So i usually use mine on standard showing for movies that have been out for a bit

Jason it is printed somewhere on the tickets that they are only four basic regular showings they are not for the 3D or the RPX. It's the same for AMC as well
