So my take on CFM. I've been to 6-8 of them. For a small, regional show during normal times the selection is pretty awesome. You will have hundreds of different corals to pick from. For me I've always found great prices on stuff I normally don't see, and (no offense to Neptune) much, much lower prices than local LFS, but you have to bargain. It's a farmers market for God's sake - bargain. I promise if you come late or stay late you can haul off a huge amount of cheap corals if you bargain for a bunch at a time. No one wants to cart them home again. I have never gone and not gotten big discounts.
My normal plan of action is try to get in early by helping someone set-up.

Then do an early spin around the room. There's dealers that will sell cheap to begin with because they want to make their "nut" back, and are worried they won't make much money. Oftern they settle down after the first hour and it's hard to get a bargain then. A couple of shows ago I hit one table up (for instance0 right at show opening. They had some gorgeous rock nems at 30-50 each. I bought ten at 15.00 each. They wanted to make sure they paid for their table right away.
Then, if you have the time, wait for the last hour. Everyone's tired, and thinking about breaking down. I promise there are great deals to be found.
P.S. Want fabulous deal??? Go to Macna or RAP and wait till the last day about 2 hours before breakdown. You can buy at 20cent on the dollar cause no one wants to cart stuff across the country again.
