Great app, support is great! Andrew helped us very fast and accurate with "problems" we were encountering. We use it to print UPS stickers and fulfill items at the same time, which streamlines the process a lot. keep up the great work!
App still in beta, so a few minor things to sort out. However, I'm using this app and it is already really good and automates the fulfilment process even further for us. Makes it a breeze to print out shipping labels and calculate the cost for shipping. It's definitely very helpful. The guys at Postmen provides really good service. Definitely check out this app and see how it can work for you.
