Amazon under investigation by US Postal Service

NEW YORK -- Amazon.com is being investigated by the U.S. Postal Service, the online retailer disclosed in the annual report it recently filed with the Securities and Exchange Commission.

In the Jan. 29 filing, Seattle-based Amazon said it learned in January that postal inspectors are investigating the company's "compliance with postal service rules." The company said it is cooperating, but provided no elaboration.

Amazon spokeswoman Patty Smith had no comment.

Peter Rendina, an inspector in the Postal Service's law enforcement arm, said the investigation is ongoing, but he declined further comment.

The probe was reported earlier by TechFlash, a tech news website.
