I have purchased a couple of windows licenses through the years - is there ANY WAY to get a discount to purchase a mac version?

I am so happy that there is a mac version of this - I have to work on one at work and i cant stand the stock app and every other app i have purchased is crud. I would love to purchase this one but it is getting expensive - i have purchased unusable - 2 to be exact this month. Thanks, Kelley
