According to the Palm Beach Post, south east locations of Dunkin declared Monday, March 9 as free iced coffee day.

But not all stores are taking part, only participating locations.

Stores in Georgia, South Florida, North Carolina, South Carolina, Michigan and Tennessee are taking part according to Bustle.com.

But the free joe isn't just a kind-hearted gesture to get tired folks through the day.  It also helps promote the new flavors tied in with the company's other retailer, Baskin Robbins, with flavors like Cookie Dough, Butter Pecan and Rocky Road the Palm Beach Post reported.

No coupon is needed, but you are limited to one free 16 ounce iced coffee at the participating locations.
