USPS shipping options in OC 2.0?

Hello,

I'm currently running 1.5.6.1 for my site and have a Stamps.com extension that allows me to very quickly and easily print labels right my admin page on the order screen. I want to upgrade to OC 2.3 but the stamps.com extension is no longer available. In fact, I don't see anything close in the extension section. So I'm wondering how you all are generating pre-paid USPS labels without having to manually copy over shipping information to stamps, endicia, or usps.com? Is Shipstation the only option?

Thanks,
Garret

Did you find a solution?
