Unless the company specifically post a discounted course (like Peter Smythe sometimes does on this forum) then i wouldn’t say so.
Those who offer a discount for doing both class 2 and class 1 will list the course as a package and the price will be slightly discounted.
You have to remember it’s not like buying a car, you can’t negotiate price based on how much you think it’s worth, training Courses are specifically priced to pay for a plethora of different costs that the training company have ranging from the fuel used on lessons to staff salaries.
Personally i just paid the full price for all of my courses as i knew fine well how much it was before i got into it.
