Its a bit of a process going through all the steps to create your account and get API authorizations, etc from USPS. Not the apps fault but worth noting. I must say that it certainly works as it should. Customer support was also fantastic in resolving any trouble I ran into during the process! Thanks for a great app.

Been struggling with shipping and hitting the right combination so that we aren’t taking a hit on every order. This makes it easy to do and has saved us a lot of money and has helped us with our sales. Definitely recommend.

Been using this for a couple weeks, including to Canada from USA, Flawless! This one definitely rates 5 stars. Thanks for a great FREE plugin that allows me to ship internationally! I rarely do that but when it’s needed it’s needed, and paying for something I may only use a few times a year just doesn’t make much sense. You fixed that for me, and I’m so grateful for that. Thank you! Don’t hesitate, it’s a fantastic plugin. You won’t be sorry!
