Interestingly, this is a problem that Indian e-commerce players tackled early on but probably due to different business dynamics. There's no dearth of courier services but none of them has the mindset of providing A-class customer experience. As a result, most of the top players handle the logistics themselves in many cities. In fact, half of their employees are associated with last mile deliveries. The result is a delightful customer experience with the top 3-4 players. Returns/exchanges are a breeze too. Time will till if it scales well while maintaining good margins.
