Kava Estonia

Seems to be a new vendor, just launched this month. As I've seen several Swedes having their cava seized by customs, thought I'd post it here. Might be worth to try. They are currently carrying SavuSavu and some type of the Vanauatu variety. Though the prices are quite hefty.
The website is only in Estonian though, so Google translate might help.
Just to mention, that I have no experience with them and unlikely that I'll order any at these prices.
