Germany-based videogame soundtrack website synSONIQ has always been a good online shop to buy various gaming CDs, including such treats as Peter McConnell's excellent Grim Fandango soundtrack CD and Michael Land's rare soundtrack for The Dig. They've unfortunately been out of stock of many goodies for a long time...
... that is until now! They've recently opened up an eBay store, and surprise surprise look what they've got: this and this.
I know it's in German, but it's all self explanatory. And yes, "Weltweit" does mean "Worldwide".
Act now, as this may be your last chance to own a piece of rare LucasArts tat. Or admittedly you could just download them here if you're feeling cheap. You dastard.
