Amazon.com, which already offers same-day delivery in New York, Philadelphia, and Seattle, is now offering the service in Boston, Washington, D.C., and Baltimore. It's expensive: $14 to $19 per delivery, plus per-pound shipping fees. But for Amazon's core user base of the lazy and wealthy, same-day shipping is a no-brainer. Why no same-day service in the Bay Area, though? Unlike the East Coast, served by Amazon's Wilmington, Del., warehouse, and Seattle, which also has a local facility, northern California gets items shipped from Fernley, Nev., outside Reno. A bit too far, we suspect for economical same-day service. After the jump, the notice from Amazon.

As an Amazon Prime member who recently shipped an order to Boston, Washington, D.C., or Baltimore, you might be interested in a new service that we've recently expanded to all three cities—same-day delivery through Local Express Delivery. Thousands of items are available. Just order before 9:15 a.m. eastern to ship to a qualifying address, choose Local Express Delivery, and your package will be delivered by 8:00 p.m. that evening.
