Title: Shipping tax, insurance and cost don't need to be sent up (if nil)

Was having trouble getting orders to be marked as shipped because even if these were nil it was defaulting them to zero and then throwing an error about changing costs after an order payment has cleared.

Now, I think these specs are right but I can't get a lot of the tests passing, so if someone with passing tests would like to validate.
