EDIT: Intrepid Hiffer has pointed out this is for Sunbutter, not sunflower seeds. Hahaha my bad.
Target is giving out free SunButter sunflower seeds in “on the go” packs. Funny, I've never had trouble transporting sunflower seeds around.
In order to make the form appear, you'll need to have a child at home aged 5-11 or fib a little about your own age.
