I've recently been exposed to the resale community that uses eBay, and it's quite impressive. Many people scour thrift stores like Goodwill for items to resell, but the process seems inefficient for both the resellers and the thrift stores. To make the process more efficient for both and to increase demand for goods, I imagine that there could be pre-processing services provided to both sellers and buyers, which take photos of groupings of goods and use ML to provide likely metadata about each good and assemble thumbnail photos of each good. They could then be posted to a central "marketplace" area that is accessible to buyers.
