Usually money is good for 1 or 2 items of long term value, plus consumables, and it just generally piles up purposeless in the late game.
In my current game I have bought 2 scrolls of acquirement, 4 manuals for useful skills, and 2 consumables.
There’s items in the shop that I want to buy, but can’t afford, and are worth planning around. Like 2 manuals of throwing & stealth each, 1 manual of dodging, 1 more scroll of acquirement, and 2 pieces of good (for me) artefact jewellery.
I only hope this won’t be seen as an “error” that needs to be “fixed”.
