In the replica industry, a "Group Buy" is when 50 buyers pool their money to commission a factory to produce a specific handbag or sneaker model. According to leaked chat logs, refers to a specific Group Buy where the production run cost 50,000 Chinese Yuan (RMB). This batch is rumored to be for a specific "God Tier" Birkin 35 replica that uses authentic leather. Searches for this term are often conducted by collectors looking to see if any "slots" (availability) remain for that specific high-stakes production run.
