Here's the new magazine with the ad (page 23):
starcineplex.ca
Looks like it launches Wednesday:
cineclub.ca
The ad specifically mentions Opening Nights, so at least that won't be restricted, it appears.
The fine print on this is going to be key. Will there be any rollover or grace period on unused months, or is it a hard line one per calendar month? Will it include the "premium" options like AVX, or will you have to pay extra for those, or will they be excluded entirely?
