Top 5 Things You Need to Know About Dunkin’ Free Coffee on May 19

• Yes, it’s real. On Sunday, May 19, participating Dunkin’ locations across the U.S. are giving away one free medium hot or iced coffee per customer—no purchase necessary.
• No coupon required. Just walk in (or hit the drive-thru) and ask for a medium coffee. They’re doing this to celebrate National Coffee Day—or, more accurately, because they’ve discovered this date is when people are most desperate for a caffeine boost before summer officially kicks off.
• Time window matters. The offer is typically valid only during regular store hours, but don’t sleep in: many locations stop handing out freebies by early afternoon, so plan your visit before 2 p.m. local time.
• You can customize (within reason). The free medium coffee includes your choice of hot or iced, and you can add cream, sugar, or flavor swirls free of charge. Extra espresso shots, cold foam, or nondairy milk alternatives? Those might cost extra.
• Limit one per person. Sorry, you can’t load up on free coffee for the whole week—this is a one-and-done deal. Bring a friend if you want back-to-back caffeine hits.
