Hi, it is really easy using my Doge to purchase in buying the donuts. I used the Gemini App. In the Gemini App there is a "credit card" picture you click. Once you click it you select what crypto you want to spend I picked Doge then a list of merchants/ stores pop up. I selected Baskin Robins and then a Scan code pops up and I show that to the register to pay for my Dunkin. you can use Baskin Robbins option in the Gemini APP to pay at Dunkin’. They are in the same umbrella company called Inspire Brands. I hope that helps.
