I've tried different times of day to sell music discs, and found out the market was pretty small. So here I run to the forums.
If you catch me online, you can buy from me the complete set of 12 music discs, for 28k. (Open to some slight bargain). I have 2 sets available right now. (Almost 3, just need one more disc)
The two rarest discs (wait and 11) can be bought together for 18k.
All other discs are for sale, depending on availability.
Fine print: I will only perform transactions when I am on the server.
