Thought that Dunkin' Perks Rewards could use a thread. Here's how it works: Buy a rechargeable gift card and register it at dunkindonuts.com. For every $20 you spend you get $1 in Dunkin' Dollar sent in the mail. If you set your card up to autorecharge at the website and it successfully autorecharged in the calendar month - then you receive $2 Dunkin Dollars for every $20 you spend on the card. I autorecharge with my mileage c.c. so I earn miles. They send these things snail mail, and probably at a bulk rate... earned my reward for April and still hasn't shown up in the mail (although I did get a confirmation email). You also get a certificate for a free coffee on your birthday. And I got a postcard yesterday for a free drink just for signing up. Seems to be a decent loyalty program for serial coffee drinkers (like myself). And there are other periodic promotions like this current one: Spend $20 on your card between May 19-25th and get $5 Dunkin' Dollars.
