Welcome!
A group buy is hosted by someone who has a connection with the retailers/studios making premium releases. They secure an amount of copies and then offer them up to members on a VIP or first-come-first-served basis
What you see there is a Group Buy for that release. The price you pay is to reserve a copy at retail price, plus fees for the hosts work and to support this platform
Not all Group Buys include shipping in the initial payment, so make sure to read through all the terms before you buy, as you can’t pull out if you change your mind
