Amazon US items (available to us)

[Sinnertwin]

I was looking at those listings last night, and if I’m not mistaken (as I’ve ever only bought a couple of things off Amazon Us), they’d charge shipping separately regardless if the pre-orders become available at the same time?

Naw, in my experience you pay shipping once and then as a "gesture of goodwill" Amazon will ship each item as they become available
Perhaps some one else can verify that they've had the same happen to them too?
