Short term trading weekend lounge: 8-10 jan, page-10

Has anyone ever tried (and/or had any success) negotiating brokerage rates with commsec?

I use both CMC and Commsec, but looking at a report for the last 6 months is scary:

• For the Period:  01 Jun 2015 to 08 Jan 2016
• Total Confirmations: 352
• Total Brokerage: $6,637

This is just my Commsec ones, not sure of an easy report out of CMC.
