Does Amazon link accounts?
Does Amazon look at the history on my accounts in other countries (Amazon.com; Amazon.co.uk; Amazon.fr) when I'm contacting them for a refund?
Or could I easily do, say, 2 refunds on US Amazon, 2 refunds on British Amazon, 2 on French and Italian?
They aren't linked, so what you're planning should be possible.
No not link but be safe anyway
