I sell on multiple online avenues and I am currently using Ship Station to integrate all of my online avenues but NRO. Ship station offers a free Magento extension, but to my understanding hasn't been tested with NRO. This would be an awesome addition to NRO. Imagine 1 button order management and shipping label printing! I sometimes have 250 plus orders on Monday mornings between all of my online avenues and Ship Station really saves me some time!
