Return Auctions feature products that have been returned to the retailer for refund or replacement. They may be unwanted items, or usually, items that did not meet the customers expectation for some reason, or, faulty. Australia has very strong consumer protection laws and most major retailers offer fair return policies to their customers.

Return auctions are popular with resellers who recycle and/or refurbish items and return them to the used marketplace either via eBay, Facebook Marketplace, or their own online store. Otherwise people may purchase the items for their parts value.
