My best find was in 2002. PC release of Blood Omen for 10 zł (that's 2,50€). It's the only physical copy of the PC version I have ever seen. I had NO idea what an epic deal that would turn out to be.

Edit: On a different note: I just discovered the German version of Silver on my shelf. And it has the Burger King logo on it. I must have borrowed it from my cousin ten years ago. I should probably return it... but not without inserting the epic German audio into my GOG release. :D
Has there ever even been a digital release of Freedom Fighters? oO
