A list of sets you can't order

[RF_InSAnE]

The unavailable titles aren't removed from the list. Just look for Full Metal Panic, those are there. Also Ayashi No Ceres from FX is out of print, so it isn't available anymore, but it does show up in the database.
Besides, I don't think it's a good idea to simply remove those titles from the database, because there are people (including myself) who use this site as a database of reviews for the titles. This isn't the only place I buy dvd's you know.
If the titles no longer available are removed from the list, the reviews would disappear as well. I for one would hate to see that happen, for this is the only site I know with a decent reviews system (not just a number of stars, but also an explanation).

So removing the titles is not an option, if I may say so.
