I am from the biggest port town in south america, I remember when I was a kid some of the local shops would sell blank CDs incredibly cheap. This was around 1999 so blank CDs were not quite so cheap yet.

Eventually I found out what was really happening, thieves somehow got notice of container ships with blank CDs and were breaking into those to steal the CDs. A single container could keep a city fed (and all its modded playstation 1) for years.
