Purchase a coupon book for your city. Coupon books like Entertainment Values often contain discount coupons for specific movie theaters. Pay attention to the fine print on the coupon, which states how many tickets can be purchased at discount rates and any restrictions about the time of day that they can be purchased.
Look for food and merchandise promotions. Promotional coupons for discount movie tickets are often included on food and merchandise packaging or can be redeemed online by entering in a provided code. Some promotions require you to purchase a certain number of products, or to send in proof or purchase in order to receive discounted tickets.
Contact individual theaters to see if they are running promotions. Some theaters offer cards that offer a free movie after so many tickets are bought and stamped onto the card. Other theaters show movies at discounted rates at certain times of the day.
Theaters can even host discounted or free family film festivals or back-to-back showings of family movies. These may not be first-run movies, but the experience of seeing a movie in the theater can still make it worth attending.
