After less than a year of partnering with same-day grocery delivery service Instacart, supermarket giant Kroger announced it’s expanding the service to another 75 markets by late October. That increase means Instacart will be available at more than 1,600 Kroger stores and makes the San Francisco-based company Kroger’s main delivery provider (it uses Uber and Shipt in some markets).

“We are redefining the customer experience through Restock Kroger by rapidly accelerating our customer coverage area for seamless shopping, giving our shoppers the choice of stores, delivery, curbside pickup or ship to your door,” said Matt Thompson, Kroger’s digital vice president of ClickList.
