Query: dirty trick

I have started collecting the real mcCoys and now have seasons 1 2 and 3. I went to see if season 4 is available yet and they have combined season 3 and 4. You can't get just season 4!! I don't want another copy of season 3!! What a dirty trick. Sure hope they don't continue to do this.
