I was actually able to hide the $0.00 products pricing using the 'Hide Price if $0' contribution with some minor modifications.
One thing that would be nice would be the ability to give customers a QUANTITY discount above and beyond their normal discount. For example, I've got some customers who get good price breaks but only when they buy 50 or 100 units at a time but if they don't buy that many I want them to pay normal reseller pricing (which is still less than retail pricing)...
Basically just add a quantity discount for that particular group on each items price - so for each price on an item I could also add a quantity price and the number of units to qualify for that price...
Just a thought ;)
