Dunkin’ Donuts has partnered with MapQuest on Myicedcoffee.com, which lets you plan road trips and find Dunkin’ locations nationwide. “It’s really important for us to defend our leadership in iced coffee,” Scott Hudler, client director of marketing, tells the Boston Globe. A bold assertion, but maybe questionable once winter rolls around. “Everyone wants to know where the Dunkin’ is when they’re on the road,” says Dave Tryder, Dunkin manager of relationship marketing, in the same story. I usually want to know the most direct route to my destination, but that’s just me. A tie-in with the Simpsons movie would be a no-brainer: “Mmm, basically accurate yet confusing directions to donuts.” I’m tempted to suggest Gold’s Gym or Weight Watchers develop a complementary service, but that would be a cheap shot. Besides, I could go for a chocolate frosted right about now.
