Yes, I think a lot of us who still use V4 don't need to buy a lot of stuff for her because we already have so much. I have fifteen years worth of stuff.

And it's often so cheap, because it's older. You can get all kinds of characters for her for $3.50, even less.  DAZ sometimes gives away V4 bundles, and often puts their older items on deep discount. 

I still buy a lot of stuff for V4, but I rarely pay more than a few bucks for anything. That's the market these days. Which is probably why the vendors don't make stuff for her any more.
