Where are you shipping from and to? Have you logged into UPS to see what the correct shipping amount is?
It looks like you are charging whatever is returned from UPS + $4.
You have it set to ship each item individually.
So your results are consistent with a $11.38 charge to ship with UPS.
Maybe try setting it to ship in a single box. That will lower the amount instead of the ship items individually setting you are using now.
