Not everyone paid direct to Jack.. many went through distributors.
Those that did deal direct with Jack would know wether its air freight or sea i would imagine. If you chose air then its easily shipped in appropriate order, if sea was your choice then it would make sense to have containers deal with this.
Mind you, a distributor would have say 30 games or more coming and so these would all go in one container with room to spare and could be here in 4 weeks or so. If individual sea freight then it can still be sent as a single item and would go in a general cargo shipment, this does however take longer.

Theres absolutely no reason why this cant be done Cavey
