Issue preventing checkout

There was a payment issue:

We take credit card (processed by Shopify) or PayPal. 
Sometimes errors can occur, often because our shop is in Japan while you are in a different country. If one payment method fails, we recommend trying another. 
Please send us an email at support@shi-zen.shop if nothing works.

Shipping was too expensive:

International shipping is expensive... 
When choosing our shipping companies, we try to balance affordability with reliable service and speed. We want you to get your package on time and without hassle, and promise to make sure that you are satisfied with the delivery. 

I changed my mind:

That's totally fine! Please don't feel any pressure to purchase. We'll be here if you decide to come back later :)
