 Dunkin’ Donuts 
 
 Though “donuts” is in the name, the main attraction for many fans of this national chain is the coffee. Krispy Kreme (KKD) is giving out free small coffees and glazed doughnuts, along with $1 discounts on other drinks. You're probably drinking coffee at the wrong time of day. Wawa 
 
 This East Coast convenience store chain with a cult following is offering a free coffee in the size of your choice at their 680+ locations — a deal that’s sure to make their devoted fan base love them even more. The effort aims to alleviate a twofold problem for coffee farmers: aging trees and a fungus called "coffee rust" that slows or kills production of coffee cherries.
– Today is National Coffee Day in America, and it's worth celebrating if for no other reason than chains all over the country are offering free cups of joe. Yahoo has a comprehensive list, which includes Dunkin' Donuts (free medium cup), Krispy Kreme (free cup, plus a free doughnut), and Peet's (free cup with breakfast item). Alas, no free cup at Starbucks, but the chain is launching a yearlong project to provide trees to coffee farmers, reports CNNMoney. The chain will donate 70 cents (the cost of a tree) for every bag of coffee bought in the US. Other reasons to partake: While at work: Fortune rounds up a series of studies finding, among other things, that coffee makes you more perceptive and that taking a coffee break with co-workers is a boon for all. Health: Take them with the appropriate grains of salt, but studies have claimed health benefits ranging from cleaner arteries to better vision to a reduced risk of ailments such as melanoma and multiple sclerosis.
