As in $XXX or $XXXX

I'm also so focused on subscription revenue that I forgot to clarify that. Get a few $XXXX/month businesses and you'll have six figure annual revenue before you know it.

Do you mean you haven't heard "three", or "figures"? Because you've definitely heard "six figures".

One of those cases where you've heard "three" and "figures" but not "three figures" :P

(I've probably heard it used only a few times in my life)

Oh, right. Same here, come to think of it. I wonder what other cliche phrases we can ruin.
