Just in time for last-minute holiday shoppers, one of the most exclusive flash sales yet is about to hit Manhattan. On Dec. 20, for the first time in its history, the Federal Bureau of Investigation will open its New York store at 26 Federal Plaza to federal employees for a limited time.

Selling a full line of FBI-branded clothing and merchandise—hats, t-shirts, sweatshirts, jackets, patches, pens and coins—the store will only be open a brief four hours, from 11 a.m. to 3 p.m. Some items are priced as low as $2, boasted an email sent earlier this week to federal staffers. The store is run by the FBI Recreation Association, a nonprofit headquartered in Washington D.C. Representatives did not return calls requesting comment about this flash sale opportunity.

"The FBIRA board members would like to invite all of their federal partners for a lunch time of holiday shopping," read the email.

In keeping with the exclusive nature of the event, potential shoppers will need to display building and agency IDs and be accompanied by an FBI escort from the lobby's elevator bank servicing the 22nd through 29th floor. No cell phones or other electronic equipment will be permitted. The first-time opportunity to own G-men gear has excited federal employees. The email did not specify which floor the FBI store is on.

"I have a feeling a lot of people are going to go," said one federal employee. "There's going to be a line around the elevator banks."

Of course, hopeful New Yorkers expecting to purchase the same FBI swag seen on Fringe or Without a Trace might be disappointed. According to an FBI spokeswoman, the store will not be selling raid jackets or any type of FBI-branded arrest equipment. Most items are novelty.

"Nothing to do with official business would ever be sold to the general public or even to federal employees," she said.
