Less arbitrage and more benefit to Instacart/the stores. Who probably knows a store better: random Instacart shopper or employee of the store? In the end, Instacart gets faster fulfillment and more accurate fulfillment for a price (whatever cut Kroger etc. take to do this). The stores get direct access to the order data and can then stock their stores better, capture the extra demand, and keep their employees engaged in revenue generating work (Instacart probably pays the store for this service of in-house shopping)
