Drivers choose when and where they will deliver, and their delivery price. It's more like Airbnb's business model than Uber or Instacart.
My big question for which I can't get an answer, no matter how many times I ask (in the context of Instacard and similar): How does payment works? People pay through credit card on the app, the money is capped, then capped again, then goes to the drivers after a month? How do the drivers pay for the groceries?
1 - they pay eggler (who in turn pays the driver) for the delivery
2 - they pay Walmart for the groceries which the Eggler driver will deliver.
How do you deal with bootstrapping, that is getting customers without drivers or drivers without customers?
