AMC has released a new coupon for their Large Coke and Large popcorn snack combo at AMC theaters nationwide! My friend and I split this last time we went to a movie and I think it was $18ish. so $9-10 for enough to share is awesome. Print coupon here.
Note: if you and your movie buddy prefer different popcorn toppings, make sure to sneak a bag or a bowl in your handbag to divvy up the goods. My friend and I were told we had to pay the full price of a large popcorn just for her to get a bag to split the popcorn we had into.
