USPS investigating Amazon

The US Postal Service is investigating e-commerce giant Amazon.com regaurding its mailing compliance, although details are not forthcoming.

In its fourth quarter financial report issued last week, the e-commerce company made brief mention of the Postal Service “investigating our compliance with Postal Service rules, and we are cooperating.”

A spokesman for the USPS Postal Inspection Service, Peter Rendina, said the agency is conducting an investigation into Amazon's mailing compliance but could not elaborate due to the ongoing investigation.

A message left with Amazon.com representatives was not returned in time for press deadlines.
