Being in the graphic design business, it’s frustrating what a customer doesn’t send their branding-designated fonts. Adobe has a lot available, but not everything.

I’ve found that the best resource for finding expensive or niche fonts is VK.com. There’s a big font sharing community there, and you can usually find what you’re looking for.

You don’t need to sign up, you can search the whole site by googling site vk.com "font" "your font name here"
