Amazon is getting serious about same-day delivery: today the company rolled out its instant gratification service across more US cities including New York City, Philadelphia, Washington DC, Baltimore, Dallas, and Indianapolis. They pay $9.98 for the first item and $0.99 for each additional one, so the convenience of same-day delivery demands a higher premium if youre not paying Amazon $99 for Prime. Orders must be placed by noon to be eligible, and Amazon offers same-day deliveries seven days a week. Over 1 million items are eligible for same-day delivery, according to Amazon, though theyre all typically small in size.
