Regal is really pushing to get people into theaters this month. For every $50 of Regal giftcards purchased, they will credit your Regal rewards card with 50 points. That is a FREE popcorn, soda, or movie ticket depending on where your points are at.
Every Monday is Movie Monday at Regal. For some reason, this is sponsored by Yahoo. You can get a coupon for a FREE drink when you buy a popcorn. This could be useful, especially if you go to The Hobbit marathon on Monday, December 15th. Mondays also have a featured $2 candy for rewards members.
Tuesdays, Regal offers a $2 small popcorn to cardholders. I also have to mention that AARP members get $3 off a popcorn/soda combo. I use that one all the time.
This week only (12/1-12/7 but perhaps it will be extended), Regal is offering buy two tickets to Interstellar and get one FREE. This is a lot weaker than their previous BOGO offerings but is still a good offer for larger than couple size.
