Why would it ever cost almost $400.00 to change the fluid in a DSG transmission? on 2013 Volkswagen Passat

I went to a dealer for the 20000 mile service and asked about the cost to change the transmission fluid. They stated that the fluid must be changed at 40000 miles, and the cost today would be $375.00.

Their fluid is marked up 300%.
It's the same with most all European makes!!
The fluid is $30 per quart plus an hour in labor to flush. Price sounds correct for that job.
