Hmm, I do have to agree that LFS do up their price by 4X of what they get their fish for. But look at it like this though, they have to pay their employee's, pay their rental bills, pay the electricity bills(you bet they use A LOT of it, especially in the saltwater department), pay for the insurance etc etc etc. Overall, as for what I see it. Most of the fish in all LFS prices doesn't change that much. Probably cost more by $10 or less by $10, and yes I know that $10 can get you another fish. But hey, where are you buying fish next without LFS? No LFS = no online sale = no more wholesales = dead hobby.
I guess the only way that I see that its really over price is paying for an old fish that is going to die sooner than a little fish of the same species.
