In the neighborhood of 6000, across about 200 albums. Of those, I actually possess the disc for about 150 of the albums and the rest were digitally purchased. The only thing interesting about any of this is the vast bulk of the collection was purchased either during the period from November 2004 - January 2006, and October 2006 - October 2007, when I was deployed with the US Army. Amazon will, in fact, deliver to a war-zone and as such is the greatest store on the planet.
