It' not really a free half point. It's on Fridays night to early Saturday morning and it's really a free 1/4 point. Instead of having you move the spread 1/2 point either way like Skybook, they display the lines with a 1/2 point differential. So you'll see -4.5/+5, -7/+7.5, -11/+11.5 and so on. Not a bad promo at all, but it's not really a free half point.
