Yeah, the subject barely makes sense to me too. Let's say I send a visitor to an ebay search results page via my CJ affiliate link, and then during that same session they perform additional searches on ebay's website.. bidding on several items they see. Do I get paid for every winning auction that they entered during that session? Or do I only get paid for winning auctions generated from that first results page? I'm confused. Thanks.
If they go through your link and buy a washer, then they search for a yacht, and win both, you get paid for both.
Remember, you only get paid if they actually "Win" the auction. Using the "Buy It Now" feature can be considered "Winning". As long as your cookie isn't overwritten, it does it for all items within 30 days.
