This is like saying: "Yeah, you can run stop signs, I've done it tons without getting a ticket or into an accident."
As others have said, please stop shipping without being certified. I don't want irresponsible people like you, to ruin it for people like me and others. Get certified. It's free to do and relatively easy. If you have a good rep you could get it done in two weeks.
Same for the OP, just do it. Why risk it for yourself and others, when it takes virtually nothing to get certified.
