To all you NAS veterans - is it better to I return my items in store, or by mail. And when by mail, can I return items from from two orders, but which arrived in 4 separate boxes, all in the same box? If it makes a difference, my Born boots came straight from the manufacturer.

I don't live near a Nordstrom, but will be driving by one in a few days -it will be a bit inconvenient to stop by but doable.
