Labor time and rate for cooling flush

Hi Folks
We are redoing our menus and I'd like to get a feel for what you all are charging to power flush the cooling system(s). Right now I'm just looking at GM vehicles. Around here the dealer average appears to be about $90 plus tax to the customer. We are using Winn's products and figure with the flush kit and Dexcool we have about $45 retail in parts; .08 @$50 for labor.
Also, when you all quote pricing to the customer, do you quote a TOTAL price including tax and shop supplies? Are there instances or specific operations where you do not charge shop supplies? (I'm a parts guy so don't hold that against me!) Thanks for your help!!
