supergood coffee review for Swap Global

I have to agree with "Camera Butter". The app looks slick, but it's impossible to figure out how to actually set it up. I tried a few things, but it's still not showing up in the checkout. There aren't many options other than to add a 'zone' and have it adjust the pricing for you - no mention of duties being calculated automatically or anything, and it's not showing up in the checkout now that I've setup everything there is to setup. It's very basic but doesn't seem to actually do anything?
