I know I am cross posting, but I wanted to make sure that people can find this if they need it. I patched together a very awkward solution to the Staffelpreis vs. Specials problem and contributed it here:

There are many limitations to this solution, and it is anything but elegant, but no one else was making one so there it is. Hopefully programmers who are much more skilled than I will be able to refine it a little. Or rewrite it - better yet.
