Every published deploy eats 15 credits. And since auto-publish is on by default, every time I push a commit for my daily Weird Web October submissions, Netlify's in the corner like:
“Thanks! That'll be 15 credits, please.”
I'll own this one. I didn't read the fine print on credits until I watched my balance vanish like samples at Costco. I've got 8 commits worth of credits left... and 21 days to go in the challenge. 😬
