UPS Incorrectly Charging Extra - Notify Customers When This Happens

[blurays4every1]

Sometimes USPS charges you extra for a shipping service that you didn't use, but for me it's mainly UPS where they state it was a different weight. I asked Ship Station if they could send out notifications when they do charge you extra. They said post in here of the idea and maybe it will happen.

Of course I assume it won't happen, but get out my frustration on UPS overcharging and I have to file claims when they do.
