The convenience store chain 7-Eleven transformed 11 of its stores in the U.S. and one in Canada into Kwik-E-Marts, at the cost of approximately $10 million. 7-Eleven also sold "Simpsons"-themed merchandise in many of its stores. This included "Squishees", "Buzz Cola", "Krusty-O's" Cereal, and "Pink Movie Donuts". This promotion resulted in a 30% increase in profits for the altered 7-Eleven stores. Homer performed a special animated opening monologue for the edition of July 24, 2007 of "The Tonight Show with Jay Leno", as part of another promotion.
