I have no easy way to get these suckers out of the tree, and I don't do anything to grow them. Hell, they even climbed up there and got them for me. $10 for no work on a tree I don't want and got for free is a pretty good deal.
Somehow I doubt the Columbian man who works at the Publix down the road would have wanted to pay me ~$100 for a bunch of yellow coconuts anyway.
I told him "give me whatever you think is fair for them". I would have given them to him free if he asked.
