I'm looking for a product oriented resale site like Boardgamegeek.com's used board game section, or G2a.com that is product oriented (rather than seller oriented like Etsy). And is as turnkey as possible (Wordpress plugin, Magento Commerce add-on, etc). Open source, or proprietary software sold with source is acceptable as well. The language the code is written in is not a huge concern.
Key features:
- Seller registration and item listing tools.
- Search by product -> then list sellers offering that product.
- Seller reviews/rating system
- Cart and checkout preferred, but if necessary, I can bridge it to a shopping cart
