Hello, I am soundtrack geek and I wanted to purchase all of WoW's soundtracks, but sadly I am not able to because there are none at eu.blizz store :(. I searched support forums and there was one inquery about this just a year ago and one of your employees responded this

Hi Frozzle,

We are going to pass this on for investigation but I can't say if it's intended or not at this time. Thanks for the report! :)

But sadly, there was no further info about this issue, I don't really want to buy a collector editions of wow and past expansions just for having soundtracks, but I think I will have to.
