You're looking at it wrong. They don't take an hour to deliver your items. The driver should, in theory, be running around grabbing the items you requested (which are put into the store based on them being quickly available: "All items on Instacart are sourced from the stores closest to you") and the items of other orders in their queue. Because of the locality, it may take them only a few minutes to get you those items, not a full hour. You're also assuming they don't charge a small markup on each item, thereby offsetting the size of each order.
