Got my windows tinted......need advice now to get it redone

[yarisitis]

I got my 3-door liftback tinted last week. 5% on the back 3 windows and 15% on the two side windows for $140.

Now that I've spent some time driving it, I'm afraid I went too dark in the back. I don't feel comfortable driving at night because I can hardly see a thing. I can see out of the two 15% side windows pretty well at night so I think I'll keep those.

I called the tint place back and asked them how much they would charge to have the 3 back windows re-tinted to 15% to match the two side windows. At first I was told $75, but that's more than half of what I paid, so then he said $65 cash.

Do you guys think $65 is a fair price to have the 3 back windows re-tinted?
