Etsy is now able to print labels for much cheaper price:

They support USPS and Fedex. Much like Stamps.com.
Please add Etsy as an Integration Carrier and allow to print label via Etsy's supported carrier.
Etsy is doing the same thing as ShipStation. I do not understand how they would qualify as a carrier. In my experience, they're about the same pricing. With my Etsy shipments, except for international shipments, I tend to stick with ShipStation.
