To promote the up-and-coming Simpsons movie, a few lucky 7-Eleven convenience stores across North America have been converted into Kwik-E-Marts. Literally every detail has been thought of to bring the Kwik-E-Marts to life: Buzz Cola, Squishee machines and even Krusty-Os, among other things. This is one of the coolest and most clever marketing campaigns ever - no wonder the opening of the Burbank, California Kwik-E-Mart created lines around the block that lasted most of the day.
