Trademe is an auction and classifieds website based in New Zealand. It features classified ads and auctions for buyers in New Zealand and Australia, and sellers around the globe. Buyers can ask questions on most auctions, which is where ZenTrade comes in.
ZenTrade takes auction questions and pulls them into Zendesk as a ticket. A Ticket Sidebar App shows auction details. The first public reply to the question will answer the Trademe question. Subsequent comments will add a sellers note to the auction.
