The S.E.M. version of Feminine has been out for exactly a year and is still available
and has long been a definitive version if you're interested.
That €500 version of the Braxton may be one of the signed ones that he offered and I picked up a while back.
I haven't checked yet.
Also, Julius Eastman has been one of those composers who's had a very strong presence in the "new music"
or "contemporary classical" or whatever it's called these days for decades - and there are, especially, young
artists of all kinds who want his work, so, 24 hours?, I don't know, but within 72? Yup, fer sure!
<<< Just looked at that Braxton, and it doesn't say anything about "signed",
but it is sealed and sold by an entrepreneurial spirit from Germany.
Don't expect that to be the norm - at least while Braxton is alive.
