I am a user looking to buy cheap manga from a long series. A strategy is to find a seller with as many different books in the series as I can find. These series are way too long for the multi book search. Id love a search mode that, when you search for something generic that returns multiple ISBNs, you can see the results by seller. For example, if I look up “Haikyuu” and toggle on this mode, instead of results with individual listings, I get a list of sellers with Haikyuu titles in their store, sorted by the person with the most matches. I’d use this result to prioritize who I shop from.
