Quality Rolling
Buy lower quality in one city, reroll at a repair station, and sell higher quality — pick cities or use Auto for cheapest buy / best sell hubs.
Scanning 100 items · qualities 1–5 · buy auto (cheapest) · sell auto (best)
Tip: start at 80–100 items, then raise catalogue size if the desk looks thin — qualities × cities is the heaviest Free scan.
