Dunkin Donuts Perks card is great. I just started using it 3? weeks ago, and I've gotten 4 free any size coffees and a free 24oz travel mug that is $0.50 cheaper to refill than a normal 24oz coffee.
I think it works out to about every $12.50 spent gets you a free any size coffee. Gotta use the app or hold onto the receipt w/ the free coffee coupon though. I either clip the coupon to my visor or stick it in my wallet w/ the perks card.
Jew. Be careful or Steez will accuse you of self-loathing as a defining characteristic.
