For those who can’t wait to get their Amazon package, the wait may be minimized. Amazon has struck a deal with the United States Postal Service to include Sunday delivery of packages to its customers. The new delivery agreement went into effect this past weekend, with packages being delivered in New York City and Los Angeles. Right now, Amazon’s Sunday delivery is only in effect for these areas but the company hopes to expand to include a larger portion of the U.S. by 2014. It is unknown is the same treatment will be given to Amazon’s international customers.

Amazon Prime customers can take advantage of this expedited shipping at no additional cost. Customers, who are not part of the popular Prime service, can also take advantage of Sunday delivery when they choose the free five to eight day shipping on orders of at least $35, instead of the original $25.

Amazon hopes that by adding Sunday delivery they will see an increase growth in sales. For them success is all about selection, low prices, and delivery speed. Amazon has already spent billions of dollars building additional warehouses to help speed up package delivery. Adding an additional day increases the speed in which you will see your package.

The new deal not only helps Amazon boost their business but also gives the USPS a much needed source of revenue.
