Thank you Peter. That all makes good sense to me now. some of it I 
recognized, while other parts weren't quite as familiar.

Here's what I've got now for the CommonAdjust directive:
CommonAdjust    products:price, -50%, ;$,
==products, "&($item->{prod_group}=~/Gifts/ ? 0 : '-20%')"

The problem I'm running into is that "first" it applies the 50% discount 
to the item's retail price and then applies the 20% discount on top of 
that. I'm still working on wraping my brain around everything thats 
going on with CommonAdjust, atoms and the like, so its not all making 
sense yet.

At any rate, now for all items who have a prod_group value of "Gifts" 
I've got a 70% discount happening. Might you have an idea where I'm 
going wrong?
