Sprouts Farmers Market announced it will expand home delivery service to its major markets across the country through a new partnership with Instacart. Customers will be able to enjoy quick, convenient delivery of thousands of fresh, natural and organic products from Sprouts by simply visiting delivery.sprouts.com, the Instacart website or mobile app, where they can choose to have their groceries delivered same-day within one or two hours, or schedule a delivery for later in the week. Sprouts, which currently offers home delivery in eight cities across the country, will roll out the Instacart service to markets in phases, starting with select zip codes in Phoenix and Tucson, Arizona today. Additional markets will be announced at a later date.
