As of August 27th, Sprint removed the ability for any corporate discount to be applied to any lines past the 1st and 2nd. Due to this change, Sprint is now allowing customers to terminate their contracts between now and September 27th.
Discount Policy Change Notice
Effective 8/27/10, discounts will no longer apply to the monthly recurring charge for Add-a-Phone lines beyond the first two lines on family or share plans. The primary and second lines will continue to receive discounts.

You have to ask them to mark the contract "Fulfilled" for the lines of service under contract since a discount is no longer applied as signed into your contract.
