Fry's usually has them in store for $35, so check around and see if anyone's taking markdowns on them.
Shout Factory hasn't said anything about whether or not they'll be continuing the existing sets or not, so if I were you, I'd strongly consider going out and picking up a set or two, no matter the cost. Volume 1 and 3 are already out of print (rights issues expired) and getting harder and harder to locate.
Also, a reissued Volume 10 just got released recently, and I hear that's going to be a small run because of the distribution rights change over.
