I think there's a kind of 1.5 as well - Sold by Amazon, supplied by god knows who (co-mingled stock of varying authenticity - could by Amazon, could be Chinese knock off), fulfilled by Amazon.
That's actually not 1.5, that's 1 that you just described. There is no option 1 that isn't co-mingled with inventory of unknown authenticity that (unless it happens to be an item that's never had inventory sent in by a 3rd party, but you have no way of knowing that).
