I understand.
It would be $75 less $30x2.
But I think you would be able to save the activation fees.
I am not sure but I think you can save the fees if you activate online.

The activation fee is $36 but can be waived with a device upgrade.
In addition, I think you can activate as many devices on your account as you want, one at a time, and not incur any activation fees.
Many customers have numerous phones that they deactivate and activate on their account without incurring any activation fees.
