I ship over 1,000 packages per year on Etsy so I get good rates inside the platform when I purchase a shipping label. When I compare the rates, its almost 2X cheaper than ShipStation.
Example: I pay $13.75 to ship a 1KG box via Tracked Packet USA with Etsy or $22.76 with ShipStation.
How can I get those Etsy rates to work inside ShipStation?
