In July 2007, convenience store chain 7-Eleven converted 11 of its stores in the United States and one in Canada into Kwik-E-Marts for promotion of The Simpsons Movie, which was released worldwide on July 27, 2007. The promotion had long been rumored, but the locations were kept a secret until the morning of July 1, when the 12 stores were made over with industrial foam.
These 12 locations, as well as the majority of other North American 7-Elevens, will sell products found in The Simpsons, such as "Buzz Cola", "Krusty-O's" cereal, "Squishees", "Pink Movie Donuts" and other Simpsons-themed merchandise. The Squishees are basically Slurpees and sold in special collector cups and the Krusty-O's are made by Malt-O-Meal. Several other 7-Eleven items, such as sandwiches, are being sold in Simpsons-themed packaging. Another item is "Radioactive man Comic Book Edition #711", a special edition of the Radioactive Man series made by Bongo Comics. It was decided that Duff Beer would not be sold due to the movie being rated PG-13, and the promoters wanted to have "good, responsible fun," though it was noted that it was a tough decision.
