Service Item — one of the subtypes World of Warcraft files under Housing — gets this table as a focused view: the same drill-down the in-game Auction House browser applies when you filter by subcategory.
Service Item listings clear and replenish at whatever pace the in-game market sets; some subtypes trade in volume, others sit static for stretches. The price-history chart on each row's detail page makes that pattern visible at a glance.
Use the search box on the item database home page to jump to a specific item by name, or use the breadcrumb above to step back up to the full Housing category.
