You have to order it with the item you want to cover
I ordered it a few hours ago - policy documents have arrived.
Unfortunately it has an expiry date of 28/09/2023 - however they automatically add 15 days to this date to allow for delivery of the console.
The documents say "If the console takes more than 15 days to arrive, please contact us". I've just dropped them an email explaining the confirmed delivery date of 19/11/2020 and asked them to amend the policy.
If they don't get back to me, I'll ring them after I've taken delivery and explain.
Nothing indicates it must be purchased at the same time as the console - Amazon system certainly didn't stop me ordering and my paperwork arriving from "Protect my Bubble".
With a future delivery date and of course I'll have proof of purchase to back-up any claim I make, all seems fine.
