Sakis albums (2) are available in Amazon.co.uk (sort of). Here is the link:
Sakis @ Amazon.co.uk
It's only 21os Akatallilos that happens to be of linited availability and Ola kala. I suggest we go to the help pages and we request for more of Sakis albums. What do you say? After all Amazon is one of the safest and most popular places to buy anything, why not Sakis music as well?
