I find it odd that persons claiming to be professional pilots point out the "cost" of de-icing fluids and how expensive it is for the airlines. Yet, I've not spoken with a single colleague who can give me the price per liter/gallon.
I'd say Fuel is what costs the airline, not deicing fluid (seasonal item) but you don't see many pilots taking a pass on extra fuel accounted for on the OFP just to save the company some bucks.
Why scrimp on deicing fluid in a country victimized by ice and snow?
