I have plenty of customers in France due to people in the past having ordered from outside the EU to France and their kava being stoped by customs. Just a note of caution.
I can vouch for kavaclub.eu as we both supply from the same vendors. Honestly the shipping cost from the US combined with the chance of it being seized is a killer. The bottom line is that kava in the UK or Europe is going to be expensive. In the last 7 or 8 years that I have been in business I have had over £5000 GBP worth of kava seized. If you want to get your kava cheaply in the UK or EU then tell me how.
