We just upgraded a customer who is on a very old family plan. *How old was it?* It was so old, taxes and regulatory fees are not included in the monthly rate!
Because the current family plan discount cannot be combined with his old family plan discounts, his options were to (1) change all lines to current service plans or (2) change his line to a current service plan, but receive no discount, and leave the other lines alone. Either way, once any line gets changed, it cannot get changed back to its old plan. He decided on option (2).
Prior to the change, he was paying about $122 per month after tax. After changing, he's going to pay $40 for his line, and about $103 after tax for the other lines. It occurred to us that, if he changed all lines to current service plans, his bill would be an even $140 and wouldn't fluctuate every month because of tax. However, he'd been in the store for over an hour already, so he was pretty anxious to leave and said he'd just change them some other time.
