I was doing a search and I came across the following price list from a Bali wholesaler.

I don't know anything about their reputation and i can't interpret their freight rates so I don't know how much it will come up to for a minimum $500 order and nor am I going to try to itemize and break down the costs of doing business to try to determine the profit margin.
But if most wholesalers' prices are like this, its no wonder the collectors are hardly making any money. On top of that, I wonder what type of lifestyles the collectors are living and what measures they take to catch these fish? In all likelihood, indirectly we are supporting some sort of underpaid "collector" sweat shop.
