Items that are sold by third party merchants but fulfilled (shipped) by Amazon will typically arrive in a single box. They might still arrive in separate boxes if they come from different fulfillment centres. These items fulfilled by Amazon will qualify for free super saver shipping.
Items that aren't fulfilled by Amazon by from the same merchant will be consolidated and shipped (although you still have to pay as many per-item shipping charge as required.)
