September 13, 2007 - The New York Times dramatically slashed its normal rates for a full-page advertisement for MoveOn.org's ad questioning the integrity of Gen. David Petraeus, the commander of U.S. forces in Iraq......

According to Abbe Serphos, director of public relations for the Times, "the open rate for an ad of that size and type is $181,692."

A spokesman for MoveOn.org confirmed to The Post that the liberal activist group had paid only $65,000 for the ad - a reduction of more than $116,000 from the stated rate.

A Post reporter who called the Times advertising department yesterday without identifying himself was quoted a price of $167,000 for a full-page black-and-white ad on a Monday.

TOM ADDS: Jake Tapper of ABC News reports that Freedom'sWatch.org, which ran a full page ad in the NY Times on September 11, 2007, says they were charged "significantly more" than the $65,000 MoveOn.org paid for the same type and size ad.
