The companies announced on Thursday that they would continue their deeply integrated partnership.
Among the cart of services lining up to deliver your groceries—Uber, Postmates, Amazon, Google—Instacart is distinct in that it integrates deeply with some partners' operations. While a Postmates driver might stop at a grocery store, purchase an item, and deliver it, since signing on to a partnership with Whole Foods in September 2014, Instacart has hired employees who it trains specifically to shop in 80 Whole Foods stores and, in some cases, even has a dedicated checkout line in those stores.
