One-Page Checkout [Support Thread]

[lat9]

Btw, we also noticed 2 more issues:

1. in case user uncheck "shipping address same as billing address" checkbox, then select a shipping address with different country (e.g. billing address is US address, and shipping address is UK one), and then check "shipping address same as billing address" checkbox again, the shipping options list won't be updated (still the options available for UK address).

2. If user use a 100% coupon, which makes order total becomes zero, and then click on the confirm order button, he will be redirected back to checkout_one page, with error msg "Your order's details have changed. Please review the current values and re-submit."

I have reproduced issue#2 (and created an associated GitHub issue); I'll need a bit of time to attempt to reproduce the first.
