Oooo... this is ugly. You know, not everyone sells off colonies of millipora and prostratas at $20-30 a pop. I happened to need the room, and wanted it fast, so I dropped my pants. Could I have sold those pieces for 2x as much... most likely yes. Heck, I bet if I had charged $50-60 per colony, then a whole other flock would line up... the 'cherry pickers', its just that then I would have had to wait longer, and each person might only take one or two corals rather than 4-5 at a time.
Its just supply and demand guys, and WI is a mostly blue-collar area, so these things cost more to the average Joe, esp considering we are 'in the boondocks' compared to say... Cali. Most of those colonies at Atlantis I know come through San Fran, and the wholesellers there can sell you the same stuff as a whole colony for $30... its just that all the cherry pickers like Atlantis come through and pick them out and post pics of them, and then add another level to the selling and distribution of the corals, so the prices go up again. Take a look at the average Cali reef... their 'regular' pieces are what we consider 'rare'. Thats because they get to scoop them up locally at 1/4-1/3 the cost. You want cheaper corals? Move to LA/SF.
Cost of living is just different in different states. Here, we might pay 1/3 to 1/2 our income for housing (rent, mortgage, etc). Cali, it might be 3/4 or more since the cost of housing is higher. The thing is, the remaining 1/4 they have might be 2x what we have left over because the rate of pay is about 2-3x as high. So they have a smaller proportion of 'expendable income', but more of it. Also, even though housing costs more, other things like Milk, Fruit, etc... are dirt cheap there... they are grown there! And most goods are cheaper as well... cars, livestock, etc... because it all comes through the west-coast (even container cargo from Germany can come through SF/LA rather than East Coast). So being on the west-coast has its advantages.
Look at me, sure, I can order direct from Surya/Indo, or a Wholeseller in HI, but the problem is that in the end, I have to have someone in SF/LA pick it up, repackage it, and reship it to me, adding another $50-some to each box right off the bat. That means a $50 bellus angelfish just went up to $75 just because of where I live. That sorta sucks.
Other cities like Atlanta are just plain booming (where Milwaukee has been considered a dying city since WW2 when the industry started moving out), and the boom means alot of well paid people. When I was down in Atlanta, I saw a 'mini-meeting' of the Atlanta Reef Club at Cappucinno Bay, and members of the club were dropping $300-500 on corals right in front of me. There was a trophy wife who walked into one place and plopped down a $10,000 check for a 240g reef to be set up and maintained in her home... she didnt even know a lick about it!
The midwest is a lower volume market. Most companies/retailers try to make it in the east coast and west coast before expanding to the midwest, we are notorious as conservative buyers here... from electronics to dining, from cars to vacations. We spend less, so things cost more... you want cheaper corals, I hate to say it, but buy more. Then LFS's can negotiate better deals and distribution which get passed on to you. If I buy one lineatus wrasse, I will most likely have to pay $200+ dollars. If I buy 24, I can most likely get them for less than $40 a pop (then reshipped through SF so about $50-60 a pop).
