Looks like you can buy them direct, although as they are based in Chile I don't know what the postage would be:

Yes, I also found their website, yet I was hoping for an European outlet somewhere. I'm also not sure what I should think about the prices provided.

The prices look ridiculous but the Chilean peso also uses the $ symbol. Converting the prices, I thought it was quite cheap.

Ah, right. Then it is not that bad indeed.
I'll try and contact them.

No contact yet, no mail address on the website, nor any other means to connect with them.
