Anyone who enrolls beginning Monday will instead be added to a waitlist — with an indefinite wait time.

Prior to the announcement Sunday, Amazon customers have complained about a lack of available delivery time slots for Amazon Fresh or Amazon Prime Now, which shops from Whole Foods locations around the country and provides day-of delivery. In an initial effort to mitigate delays, the Seattle-based ​e-commerce company added 70 new Whole Foods pickup locations — up to 150 from just 80.

Amazon Fresh and Prime Now workers shop from the retailer’s own warehouses, as well as Whole Foods stores. The company also promises ultra-fast delivery within a few hours of the order being placed. In an apparent move to consolidate their supermarket services, Amazon suspended the Prime Pantry delivery service last month, which sells only non-perishable goods.

Since the coronavirus outbreak began, Amazon claims capacity for online orders has jumped more than 60 percent. But those who pay $119 per year for an Amazon Prime membership have complained on social media about delays and the lack of available delivery windows.

Amazon, which purchased Whole Foods Market for $13.7 billion back in 2017, said they also plan to abbreviate stores’ hours to the public so that their employees can have better access to fulfill online grocery orders. Some high-traffic locations will shut-out the public altogether, such as New York’s Bryant Park store, which sent an email to local customers on Monday morning stating they will be “will be temporarily closed to focus on grocery deliveries.”

Other locations, including Columbus Circle, Midtown East or Union Square, remain open for all shoppers.

Amazon’s 487 Whole Foods stores nationwide are already limiting the number of shoppers in the store at once, and performing daily employee temperature checks as well as requiring workers to wear masks and gloves.

The company said they soon hope to meet demand by adding more shoppers to their roster, and plans to launch a new feature that will give customers a chance to secure their virtual “place in line” — so that delivery times are distributed on a first come, first serve basis. Previously, Prime users could only hope to get lucky by shopping at a time when a shopper happened to be available.

Meanwhile, high-profile protests by workers at Whole Foods and Amazon fulfillment centers are still underway, which blame their employer for unsafe working conditions. More than 50 of Amazon’s warehouses and Whole Foods stores reportedly have confirmed COVID-19 cases.

“We still expect the combination of restricted capacity due to social distancing and customer demand will continue to make finding available delivery windows challenging for customers,” Stephenie Landry, vice president of grocery delivery at Amazon, wrote on the company’s blog. “If you are able to do so safely, we kindly encourage our customers who can to shop in-person.”
