Where are your bottlenecks? How do you produce shipping labels etc? Automation at each stage would be the key.
Although a 10x increase would catch anyone out because physically stuffing widgets in packages is likely always going to be a manual process for most people.
I guess if you have some sort of "average order" of a single popular item you could do some packing in advance when you are not quite so rushed!
