Amazon has had a stranglehold on electronics for years, taking revenue away from former brick and mortar powerhouses like Best Buy and Circuit City (RIP). With subscription plans like Amazon Prime that offers free 2-day shipping to subscribers and free shipping for orders over $35 (recently increased from $25), the online commerce company has truly become the de facto website for all online orders.

Now, the company is preparing to increase their success with news that Amazon has partnered with the United States Postal Service (USPS) to begin delivering packages on Sundays. Beginning next Sunday, November 17, Amazon will test Sunday delivery in LA and New York, and will expand to cities like Houston, Phoenix, Dallas, and New Orleans in 2014. The partnership will not only boost Amazon’s revenue, but also bring some money into the USPS itself, which has been facing dwindling business over recent years.
