It all started with rubber stamp companies, mainly... and now has spread to card making & sb'ing, paper and digital.

To try to answer your question, what me and DH had to do was send out letters in writing asking for permission to use fonts off cd's and dl's for profit. That way you also have something in writing back from the company if anyone ever decides to say you can't do that, and try to sue you.

Hint: This is why I have every CK FONT CD ever made. They were very nice & honored about the fact that I wanted to use their fonts to make cards, sb pgs, etc... You just (like in any other situation, really) have to be sure to give them Full credit... ie: "CK Font CD, Special Occasions, CK Heritage" on your product you are selling. This actually works as well with papers, stickers, stamps... any of those things used for paper crafting.

Hope this all makes sense & helps you out!

Sincerely,
