Cannot buy Scapple, help!

I have just tried several times to buy the licence for Scapple. Every time I get a message that a ‘billing zip’ is required to pay via PayPal. I have no idea what that means. We do not have post zip codes either - but what is a billing zip that the Scapple purchase requires?

Hi ravenowl…

If you’re still having difficulties purchasing Scapple, a better place for a sales enquiry might be the Literature & Latte web contact form or the appropriate email address as listed at the bottom of the same page:
