1) The email for the order and the first shipping destination (in your group order) can be 2 different people. So the shipping address would be the person in EU (or Canada, for example) and the email address of the final person in US. This would add security for loaded coins since they can't be activated & loaded by the first person receiving them (activation requires both physical code & email code).
2) The multisig coins are nowadays always E series. Keep that in mind. M serials have been discarded and they are not sent as L coins regardless, since the coins themselves will not be loaded in a multisig setup, instead a separate multisig address is loaded where the key in the coin acts as one of the signees.
Thank you for the clarification.
