MM/retailer is using DoorDash and Uber for driver/delivery so they don't pay anything. The customer pays for that service.
MM doesn't pay to carry inventory since the retailer already has the stock in the store. MM just makes a small cut on what the retailer charges them versus what MM charges the customer. All pre-negotiated.
Based upon feedback on social media I'd guess less than 5 transactions per day per store. Margins nowhere near what you think imo.
But until we see the numbers it's all guess work. I'd think he'd roll BCCI into RLTR before we ever saw MM numbers.
