Bandages are largely a classic-edition market, where first aid heals on a separate cooldown from potions and cloth prices set the cost basis. The catalog taxonomy files Bandages under Consumable. Everything listed below shares that subclass, which makes this a focused market view rather than the whole Consumable shelf.
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.
