Duh.  I'm not too proud to admit that, that is why I've asked for help!  I can accomplish what I want by hacking
the Data.pm file, but that limits what I need to do to a single catalog per source and I'd like to run more than
one catalog with different pricing from the same source.

I don't think so, look at Data.pm and the snippet of the item_pricing routine I included in the post!  As for
Vend::Cfg, these are defined and used throught the system, but yes, ItemPriceRoutine doesn't appear to be
defined and that was one of my questions, what internal routine does item_pricing call then?  and how do you
redefine ItemPriceRoutine on a catalog basis?

Christopher Miller's message this morning made reference to a subroutine call from CommonAdjust.  Chris, can you
post a sample of your ClientPricing code?  This may be a method that is more flexible than my hardcode hack...

Thanks...
