What's the street value of 100 copies?

Last Saturday night a Gamestop in Bel Air, MD was robbed at gunpoint.  And just what did these armed thugs steal?  Well yes, they did take the cash.  And 100 copies of Call of Duty: Black Ops.   Maryland represent.  Sadly, this is the second robbery of a Gamestop in the last month in the area.  Maybe they should be handing out noob tubes to all clerks.
