So the fine print is up on
https://www.cineplex.com/cineclub
From what I am reading, the monthly ticket included in the subscription price never expires, so if you don't use it in a month it rolls over forever as long as you keep up your subscription
Additional tickets cost $9.99 but you can only buy 2 per showtime (per account) and a maximum of 3 transactions per day. Looks like using a monthly ticket counts as a transaction.
There is a surcharge for 3D, 4DX, ULtraAVX, IMAX, DBOX, VIP, ScreenX. You will be charged the difference between a general admission ticket and whatever the price for upgrade is.
No commitment. cancel any time.
Looks like no limitations on showings except not valid for Cineplex Events, non feature films, special events or series.
Concession discounts don't include alcohol or any franchised restaurants operating in a Cineplex.
No discounts for kids or senior tickets.
