Yep. I never heard it was from the wild ones. I have been offered it (or to be taken to a place that has it) in my travels. A guide I hired for the day in Balil said he could take me to a place that offered it for 2 dollars a cup I think he said. You could probably get it for cheaper but that is the mark up price he quoted me. I refused of course.
