I got the Schweser III book I bought for RMB 200. Kind of disappointed since they are half the volume of the Level I and II. 
Book-0 is just review from level II, about 30 pages;
Book 1-5 are all 200 pages or so;
Book 6 has three sample exams (I did not see the two volumes ???)
Since I have finished reading the CFA institue books, I think they are more complete and better in details than Schweser notes for level III.
Anyway, support your cause!!!
