Is it normal/okay to negotiate preschool fees?

I don’t think can negotiate for the school fees. Different fees could be due to 1) diff subsidies 2) promotions during that period when they sign up/register (because schools will have different promotions/discount every now and then for new registration. 3) some school under “work Centre”, priority given to the staff at that location(eg the preschools are within the office building, school, hospital and etc), so even it’s the same “brand” of school, the school listed under work center will be cheaper, cap at $800 for “work center” preschool. Public kids still can apply but priority given to the staff at the location of the school located. You may like to check with the school for more information regarding the different fees offered.
