Yes! I used it for my annual calendar campaign to ship 1000-ish calendars a year as well as other merch – worked really well for that purpose (integrated with Shopify)
I had tried other third party shipping tools before and it ended up being the best one for my purposes.
Lol, look who comes alive when you mention “pirate ship”. 🙂
I’ve got 3 bricklink orders to fill today, so I’ll compare with shipstation prices. Is there any other site I’m behind on??
