Amazon rolled out a new shopping feature called Add to Delivery that makes impulse purchases even easier for Prime members. The way Add to Delivery works is simple. When browsing the Amazon Shopping app or Amazon.com on mobile, eligible items display a blue “Add to Delivery” button on the product page. The company previously tried addressing this with Amazon Day delivery, where customers pick one day to receive everything. Add to Delivery takes that concept further by letting you merge purchases in real time, helping Amazon consolidate shipments while giving shoppers more convenience.
