Anyone who's negotiated with Oracle know exactly what he means..
Oracle ALWAYS discount their official price list, and never ever allow customers to pay less without a fight.
Reduce your usage by 10%, that'll be a 10% price increase on what you have left. Thinking of JBoss instead of WebLogic to save money.. think again, RDBMS price goes up.
The only leverage you have with Oracle is to threaten scorched-earth
