Amazon is making it easier than ever to keep shopping after you’ve already checked out. A new feature lets users add extra items onto upcoming deliveries instead of starting a whole new order. Say you forgot to add eggs to your grocery cart or you realize an hour later that you are running low on toilet paper, now you can drop those last-minute items into your order before it ships with no need to go through checkout again. The e-commerce giant announced the feature today, calling it “Add to Delivery.” With a single tap, shoppers can add eligible items to their next scheduled delivery. Add to Delivery follows a long line of options the company has rolled out over the years to make shopping feel more flexible. Amazon Day lets users choose a specific weekday for all their packages to arrive at once. No-Rush Shipping, meanwhile, nudges shoppers to slow down their orders in exchange for discounts or credits that can be spent on digital goods like eBooks, movies, and apps. By contrast, Add to Delivery goes in the opposite direction, allowing users to buy more things and get them faster. It also comes as Amazon keeps upgrading its shipping machine. In August, the company expanded same-day grocery delivery to 2,000 U.S. cities, covering perishables like milk, meat, and seafood. That feat is powered by the logistics muscle Amazon has been building since it launched same-day delivery in 2015. For fresh groceries, the company relies on a network of temperature-controlled facilities designed to keep food safe in transit. How Add to Delivery works When users browse the Amazon Shopping app or Amazon.com on mobile, eligible items will now show a bright blue “Add to Delivery” button right on the product page. “If we can still add to your delivery that’s arriving later today or tomorrow, you’ll see the Add to Delivery option as you shop, and with one tap you’ll be done,” the company said in a press release. Tapping the button instantly adds the item to the next scheduled delivery. If a user hits the button by mistake or just changes their mind, there’s also an “Undo” option to remove an item. Items available for Add to Delivery include pantry staples, pet toys, electronics, clothes, and books. For now, Add to Delivery is exclusively available to U.S. Prime members.
