Query: Boo at the missing disc

I got the package sooner than I thought I would which was very nice and there was no damage or anything of the sort. I open up the case and one of the discs was falling out. I open it further and disc 11 was missing, which has the same episodes as volume 11. After doing research I see Eureka Seven Vol. 11 selling for $40+. I don't know what to think of this.
