Amazon continues to adjust the prices for the Nokia Lumia 920.

The Windows Phone 8 smartphone is seeing a further discount for existing AT&T customers. Current AT&T customers who are in either an individual plan or family plan can add the Lumia 920 for $39.99.

The offer is available for existing customers who want to either upgrade their device or add a new line of service.

The price change comes a little more than a week when Amazon had priced the Lumia 920 for existing AT&T customers at $69.99.

For new customers wanting to purchase the Lumia 920, the price remains the same at $19.99 when signing a two-year contract in either an individual plan or family plan.

The "Without a Service Plan" price has not changed, staying at $449.99.

The prices are still cheaper with Amazon compared to what AT&T is offering on their official website.

AT&T Online has been consistent in not changing the price of the Lumia 920, keeping the phone at $99.99 when signing a two-year contract. A one-year contract with AT&T will increase the price to $349.99 while a month-to-month price will equal the Amazon's "Without a Service Plan" price tag.

The cheapest Lumia 920 offered by AT&T Online is a refurbished matte black model for $0.99. The refurbished model is a web-exclusive offer.

The Lumia 920 smartphone has a screen size of 4.5 inches, 32GB of internal storage with 1GB of RAM, an 8-megapixel rear-facing camera with 3,264x2,448 pixels with LED flash, Bluetooth 4.0, an NFC chip, and a 2,000mAh battery capacity.
