It would be great if we would be able to display live shipping rates at WooCommerce Cart and Checkout pages utilizing Shipstation API without having to rely on third parties.
@Joshjungle Ive moved on to EasyShip even though it feels inferior in almost every way. I went simply for the in-cart calculations so that I dont have to mess with UPS accounts, a Stamps.com account, a Fedex account (etc) and then connect them to a third party plugin that would often give me issues.
Shipstation could hire a couple developers to just build and maintain an "official" third party plugin and charge an additional subscription fee for that plugin or something. Id gladly pay $5-10 a month for it.
