Hello, Perhaps you can have multiple watchlists, and then perhaps make them shareable. So, for example, I want to collect the whole series of the Star Wars Books. I would then set-that up as a discrete watchlist and monitor that list and buy off it when the price dropped. But I could then share that watchlist with others who had the same interest. Also if you have a curated watchlist, you could partner with some retailers, eg Kobo, and then allow users to buy multiple curated titles at a discount. Thanks
