Very useful app for creating shipping labels and eliminating double entry. With this tool we have been able to create a place that prints all of our Shopify and eBay labels in one place. Thanks to the address verification tool we have yet to be charged an address correction fee from FedEx, the tool has been able to catch all the customer data entry errors thus far...it has paid for itself with this feature alone many, many times over. The software works with our FedEx standard printer perfectly, which we use to print our labels and packing list.
OrderCup has been the most useful app that has been added to our Shopify store, it's become necessary, and we highly recommend it.
