This page narrows Consumable down to Utility Curio only, so the table stays scoped to one subtype instead of the full category list.
Pricing here moves the same way the rest of the catalog does — Retail pulls hourly from the Blizzard Auction House API, while the classic editions pull from TradeSkillMaster on their own cadences. Each snapshot is timestamped, so the detail page for any row below plots real movement over time.
The "Browse subcategories" links on the parent Consumable page list every other subtype if you want to compare markets side by side.
