Sorry to all my New England, Midwest, and west coast readers, but this free Orville Redenbacher's cheddar cheese popcorn is only available in 17 mostly southern states (Ohio, Michigan, Indiana, and Illinois are the outliers). I try and post freebies that are available to at least half the country, but being the giant popcorn addict I am, I can't pass this up.
And now let's get to the part where I see how many postal abbreviations I can remember off the top of my head. This offer is valid in AL, AR, GA, IL, IN, KY, LA, MI, MS, MO, NC, OH, SC, TN, TX, VA, and WV.
EDIT: Good news! Here are some more additional links for other states.
Food 4 Less: CA, IL, IN, and NE
Fred Meyer: AK, CA, ID, OR, and UT
Fry's Food: AK, AZ and ID
