Business card set up

I’m about to design a business card.
Do I set it up a single one on an artboard to size, or copy a bunch of it to fill up a full page?

Normally the way to do it is 1 on an artboard, unless specified by the printer to set it up otherwise…

I agree, normally one per artboard. But, I have dealt with printers that asked for 4 per page. Best to check with the printer ahead of time.
