Amazon made a relatively small mistake considering their scale. It's OK. They can mitigate this by stopping orders that haven't shipped.

For the items that did ship, they can contact the buyers and ask nicely for them to return the items, perhaps in exchange for an amazon gift card.

I don't think it's reasonable to put consumer "morality" in question here.
