Basically, this will be the setup for our family plan when we switch to sprint at the end of the month: Everything Family Data package w/ 4 lines Two of them will be an Evo. I will be eligible for a corporate discount of15%. Will the 15% be applied to the cost on the bill AFTER the $20 is added (aka will it be 15% off of $189.99) or before (15% taken off of $169.99 and then $20 will be tacked on to that). Also, how many bills should I expect before I start seeing the discount applied to the bill? Thanks.
