I assume you don't work at a national design firm or ad agency?

I assume this isn't meant as a compliment.
Well, you don't have to rely on my word. I assume you don't know Dov Isaacs - just google him. On this page you can read what he has to say about EPS: https://printplanet.com/threads/the-case-against-the-eps-file.268330/
Thinking that EPS is a good idea just because Shutterstock uses it, is just kind of cute. They use that EPS Illustrator 10, which for a lot of files just doesn't make any sense at all. They use EPS because it is supposed to be editable with any vector application. A lot of their files contain transparency and won't be editable in any other vector app than Illustrator (or, in case they have been created in some other app , then that one). And cannot be easily changed to be editable. So it makes no sense to supply them as EPS in the first place (PDF doesn't make so much more sense, but at least transparency would be preserved).
