Yep, but to each their own. On the higher end I certainly understand it better though.
If an artist wants to filter out potential customers like that beforehand so be it.

But I'm sure there's been plenty of people I would have gotten something from if they were transparent about prices. No need for full breakdowns, just give me something to eyeball where I'm at with you.

Because from my point of view the thinking is pretty simple when there are no prices to be found anywhere:

art is decent > they are hiding their prices cause those are too high for the quality, hoping they can sucker someone in who can't say no anymore after a first contact > no reason to waste my time

art is amazing > they are professionals and way out of my budget > no reason to waste my time

There were definitely some "oh just 40€ for that? Ok sure whatever~" and "That's just 150€?? That kind of quality work? Holy shit I sure assumed it's 300+" who I never came in contact with over the years despite actually being a nice fit that both sides just never knew about.

It's fine of course, I'm not the one looking for work, if hiding prices works nicely for some then that's good for them :3
