If you have never tried popcorn from Popcornopolis you are missing out.  I first learned about them when they were giving out free samples at Costco.  It is so good! 

Besides the offer mentioned above they are also offering free shipping with code Frshpf9, and right now if you buy 4 "cones" you get 2 free.  I would assume you would either choose the 20% off or the free shipping, not both.  They also have a spot on their site where you can see when they will be at your local Costco again with free samples!
