Buy 2 general admission movie tickets for the price of 1! It's on Virgin Mobile's website, but Bell numbers work too. I haven't tested out any other phone company numbers, but it's worth a shot punching in your number. Virgin Mobile and Bell numbers definitely work! And if you don't have a Virgin or Bell number, well...maybe a friend would be kind enough to let you use theirs :P
You'll be given a code which you can enter into the Promo Code area during the checkout process online, and voila! You can get 2 tickets for the price of one, and you can get one code each week, though they can't be used on Fridays or Saturdays.
AAAANNND if you buy a ticket for a Tuesday movie, general admission will be around $6.95, which means with the promo code you can get TWO TICKETS for $6.95! I'm planning to see a movie this upcoming Tuesday (:
The fine print:
Additional fees will apply for IMAX®, UltraAVX®, UltraAVX®3D, VIP room admission, digital 3D presentation, D-Box seating and reserved seating performances.
