Tomorrow's the last day!
After 7 years of selling courses, I'm finally doing a Black Friday sale.
I'd held off for from doing sales in general for all this time, but had some smart people get me on board with it, so I figured if I'm going to do it, I'll go big:
40% off + Flexbox Simplified for free.
