Who delivers GOAT packages?

I'm curious to know, who exactly is responsible for delivering those GOAT packages? Are they handled by a specific courier service, or is it an in-house team? And what kind of measures do they take to ensure the SAFE and timely delivery of these packages, given their potential high value and exclusivity? Additionally, are there any special requirements or protocols that customers need to follow when receiving a GOAT package? I'm eager to understand the entire process, from dispatch to delivery.
