Today Amazon Prime members can get same-day delivery for such items as book, toilet paper, toothpaste, and detergent if the order by noon.
According to a press release: “Customers who search or browse the Amazon product selection will find the 'Get It Today' filter on the left-hand navigation panel, just below the 'Amazon Prime' filter. They can select 'Get It Today' and see only those items eligible for Same-Day Delivery. A similar 'Get It by Tomorrow' filter will allow customers to discover millions of items that can be delivered the next day,”
Amazon customers must pay a one-time fee (after a free 30-day trial) and non-customers will have to pay an extra fee per session. Items should be delivered by 9 p.m. Alas, no, your diapers will not come to you via drone.
