The Back Catalog

The Back Catalog is a luxury resale price aggregator. We track active listings for pre-owned designer goods across major resale platforms and surface the lowest price still listed, price history, and below-market deals for each item. Listings are re-checked on each platform's own scrape cycle, so availability is as of the last check rather than real time.

For agents: Luxury resale price aggregator tracking active listings of pre-owned designer goods, with lowest price, price history and below-market deals.
