That said, the company is limiting the service to deliveries under $30 so it'd have to be enough McD for a good chunk of the neighborhood in the first place. The company says overs over that amount account for 50 percent of its business. As TechCrunch notes, other companies like Sprig and Munchery have brought in subscriptions for its oft-repeating customers. Postmates is also attempting to give the service an initial boost, by offering free memberships to merchant partners, staff as well as senior drivers and riders that do the actual Postmates delivering.
