Here’s a buttery good freebie just in time for summer. I know you’ll probably head out the movie theater at least once this summer so why not get some FREE buttery popcorn. All you have to do is provide your mobile number to get this tasty deal.

Here’s how it works:

• Visit a participating theater.

• Go to popcorn.yahoo.net on your phone to check in. (works like foursquare)

• Get an instant coupon for a FREE small popcorn.
