I don’t thinking was a comment specifically on external sources for prices.
It was a reply to a comment that seemed to imply that ps4 users were unable/unwilling to use any external resource.
Which is incorrect, if that was indeed the implication!
I’m on ps4 and regularly use external (not native to ps4) resources while playing Boundless, not least this specific forum!
Here are a few resources I regularly use (all credit to the creators):
