I wish there were another app to integrate shipping with Shopify. It's so very nice to not have to copy and paste shipping info to another program, but everything is far more difficult in OC than it should be. Nothing is intuitive, not even setting up and everything just seems poorly organized.
Cost also leaves something to be desired. They charge a $10 monthly fee AND the postage is more expensive than other methods (for USPS anyway).
Add on top of that, in my experience, nothing has really gone smoothly with them (perhaps catching OC at a bad time - but they've had tons of server issues causing me to use another program to send shipments out, completely defeating the purpose) and I'm really not a fan.
It's a great idea, but it doesn't see to work for me. Maybe it's because I'm on a Mac, not sure. Some labels don't generate properly and can't seem to create customs forms for USPS. If it worked properly, I'd buy it.
As a Mac user, I could not use the app (though this wasn't displayed anywhere in the content I reviewed on the service). This prevented printers to be selected - rendering the use of my thermal printer pointless.
I also found the customer service poor. They responded to some email quickly, but often waited days for questions they couldn't or didn't want to answer.
Finally, after switching to endicia, I discovered that they are about $1 more for shipping.
If you are a Mac user, do not bother with this service. *Please include this in future advertising so others don't waste hours educating themselves on how it works only to find out the hard way.
*Note: If you are a windows user and don't mind paying more for shipping, all of the functionality of OrderCup appeared to be very valuable.
