Oh man...Dell is terrible about this. Not sure what the policy is anymore (esp since they went private), but to get promoted you had implement a significant cost savings project, which ironically lead to multiple implementations and reversals of policies...they all showed a cost savings but it depended on your perspective.
I don't know anything about Dell's promotion criteria, but their consumer ordering process has to be one of the most hostile ever — I'm guessing anywhere between 50-75% of their orders get auto-cancelled by some overzealous anti-fraud and anti-reseller algorithm.
