You can get a Coporate Discount on the DC card - $10 off ($29.95) - See you local credit union or call Raliegh.
Don't know of any other.
The AT&T discount on tickets is not a published benefit. We heard about it through the grapevine. See if you can find a person in Marketing, PR, or some organization that deals with entertaining big customers or manages corporate partnerships. Keep trying out the phone chain and you may hit pay dirt.
