Some of the gray seats might be coming up for the online sale if related to bookings that are not being paid within the time limits showed onto the confirmation page.
Of course, there are some other cheaper seats. But remember what I said about the restricted view! I found a good example of what... not to buy. Those purple, 27 euro seats on top of the photo above. They're placed where pigeons nest and from there you get a spectacular view of the... chandelier :)
. Good luck everyone!
