It's poppin! Garrett Popcorn offers deal for customers to celebrate National Popcorn Day

You can enjoy some of Chicago's best popcorn at a discounted price to celebrate National Popcorn Day.

Garrett Popcorn Shops is also celebrating its 75th year and is giving customers $1.75 small popcorn bags in-shop from now through Sunday, Jan. 21, from 10 a.m. to noon.

The offer is only good for Garrett's signature recipes, which include buttery, cheesecorn, caramelcrisp or Garrett Mix. 

There's a limit of one discounted bag per transaction, the popcorn shop says.
