Free Dunkin Coffee

So Dunkin's giving away free coffee right now - hot or iced, any size you want. Just grab the Dunkin app if you don't have it already (it's free to download) and create a DD Rewards account. Then head to the Offers section and scroll down until you see the promo code box. Type in THANKYOUSPIDEY exactly like that - all caps, no spaces. Your free coffee reward will pop up immediately, but here's the catch: you've only got 7 days to use it once you add the code. I just claimed mine this morning and already planning which size iced coffee to get tomorrow.
