The largest craftable bag of the current expansion is a permanent seller, and the whole subclass tracks the cloth market that feeds it. This page narrows Container down to Bag only, so the table stays scoped to one subtype instead of the full category list.
Bag 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.
If you want the full Container category rather than only Bag, the breadcrumb above steps back up one level; otherwise the table below covers every tracked item in this subclass.
