Hey, we got more Greeks here than I thought

Good to see the Greek ebook market developing!
I'd really really love to see more publishers take this route. I've been watching myebooks.gr with interest, but haven't bought anything yet. Most books are in pdf format, and drm'ed, none of which I'm particularly willing to put up with.
In other news, it seems Kastaniotis has now gone one step further, and is experimenting with the "set your own price" feature (for the new book of Mimis Androulakis).
