You can go to court and show the window tint is removed and you will have to pay court cost. That ranges from $15-$40 depending on where it is. I did that in Doraville for my G35 and paid $35 versus the $140 fine.

Some places might offer 25%, but normally no. You would have to call around. Plus remember that the % will drop 2-3% once applied to your vehicle with the natural 70%.
