Where do I find audio CD for old Ravenloft adventures?

[Astralia123]

I've been reading old modules and have found A Light in the Belfry quite fun. However, this adventure has an audio CD, and the content is not contained in the adventure book.

How do I get this audio CD tracks? It seems much of the story are told in the audio tracks. Unfortunately I do not live in US or Europe, which means I could not buy a boxed set from Amazon or elsewhere. Is there still an online shop that sells these adventures?

I bought the First Quest box set off Amazon maybe there or eBay you could try Noble Knights I think they're called?

Edit: £90+ owch!
