$22,00 Dunkin Donuts Giftcard With Pin 22$

A "STO card" is not a Dunkin' Donuts card, but it may refer to the Stocard app, which allows you to store digital versions of your loyalty and gift cards. You can add a Dunkin' gift card to the Stocard app to create a barcode, which you can then scan at checkout in a participating Dunkin' location to pay.
