The Joyagoo Telegram group has crafted an exclusive information system specifically for AJ reselling, with the Joyagoo Spreadsheet at its core. This system is designed to enhance the efficiency and knowledge base of AJ enthusiasts and resellers alike.Within the group, there are dedicated sections such as "Release Notifications," "Experience Exchange," and "After-Sales Consultation." These sections serve as a hub for members to stay updated on the latest releases, share insights, and seek assistance when needed.The Spreadsheet forms the backbone of this system, constructing a comprehensive database of the entire AJ series. It includes detailed information on every Air Jordan model from 1985 to the present, covering color stories, material evolutions, and market heat indices.A specially developed "Collection Management Module" within the Spreadsheet allows users to document their personal AJ collection, including purchase dates, prices, and condition ratings. The Spreadsheet then automatically generates a valuation change curve for their collection, providing a visual representation of the value fluctuations over time.For classic remakes like the AJ13 Panda, the Spreadsheet offers detailed comparison images of different versions throughout history. This feature aids users in making more informed reselling decisions by understanding the nuances between various releases.For more information and to access the Joyagoo Spreadsheet, visit the official website at https://www.joyagoo.host.
