To answer briefly :

1) You are assuming that I can know in advance the
   exact date. Sorry, that's not the case : my
   main job takes too much time and I am called
   far too often on short notice for that.

2) I did posted one week ago that I would do a
   sale soon, probably at the end of the week or
   during the weekend.

3) I don't think it's more "fair" to site in front
   of one's computer to try to grab a cel during
   the first couple of seconds.

4) Yeah, Anime Chaos is always doing that. Maybe
   he should annonce when he is _not_ doing a
   sale instead -smirk-

5) I like suprises. Don't you ?
