Which maker is missing? The index grows from public product feeds, so a link to where they sell is the fastest route from this box to a crawl — but the name on its own is enough.

An address here is used once, to tell you if the brand lands. It joins no list and gets no other mail — a price watch is the thing that does, and that is a separate box on any bag's page.
