Hello, if anyone is having issues because the "place order" button doesn't enable and you are paying in a non-US country, the issue is the ZIP code. I already told the devs, but it case they haven't fixed it yet:

• Select USA as country
• Only feel ZIP code with a zip code for your country
• Select your country back and fill the stuff
• Click save

You will notice that you can fill your credit card things, or use the PayPal section and the button will be enabled.
