DoorDash has a button that lets you filter by items that are eligible for SNAP (food stamps) when ordering from a grocery store. So enough people living in poverty are using DoorDash that they thought it was worth building the feature.
Over forty million people receive SNAP benefits so even if only five percent of them use DoorDash, it's still a couple million customers. Any fees DoorDash or other delivery services add on have to be paid by the customer and cannot be charged to SNAP.
