On the Cheap - What About Iced Coffee?

While I doubt this offer is in competition with the McDonald’s offer, Dunkin’ Donuts is offering iced coffee for free at participating Dunkin’ Donuts shops.  Also, tomorrow, Thursday, May 15, 2008 from 10am-10pm  you can get one free small 16 oz. Iced Coffee per person, per visit. I find it interesting that they are offering this after their morning coffee rush, rather than marketing it to their morning coffee crowd.
