To identify and profile the top players in the luxury product resale market (luxury secondhand market) that offer the seller the opportunity for in-home evaluation of used luxury products for potential resale, provide a quote for purchasing these products, and offer to pick up the products once the quote is agreed upon. Ideally, these companies will focus on products in multiple categories. Once the top players are identified, company details should include the name of the company, market share (or another metric identifying them as a top player), types of products purchased, regions of operation, and a description of the core business model. Information will be used to develop a deep understanding of the luxury secondhand market.
