If it helps, I believe the problem is that I'm allowed to choose Croatia for "billing and shipping address", but the error is thrown on the final checkout step where I'm instructed to edit shipping address. There, Croatia isn't listed in the dropdown menu.
I seems that you have out of date list of EU countries. Please note that Croatia has been part of the European union since 2013.

Hello,

I'm unable to complete the checkout at FOSDEM store. I'm gettting the following error:

"Sorry, we are unable to ship your order. No shipping method is available for your current order and shipping address."

What seems to be the problem? I'd appreciate your help. My friends and I really don't want to miss out on this year's t-shirts.

Thank you!
