Amazon Launches Seven-day Delivery in NY and LA

Orders from Amazon.com will soon be arriving on doorsteps not just six days a week, but seven. The online megastore announced a deal on Monday with the The United States Postal Service (USPS). Amazon said the first Sunday deliveries would be made this coming weekend.

USPS spokeswoman Sue Brennan called the expanded delivery a "win/win" for Amazon and added that the postal service is interested in forming similar agreements with other retailers.

The deal comes ahead of the busy holiday shopping season. The USPS annually delivers packages on some Sundays in December.
