I buy 90% of my coral on Ebay. You just need to look at their ratings and watch what the get as final prices. Also, I REALLY would rather buy from a seller who sells WYSIWYG. That way I'm rarely surprised by getting a super tiny frag!
I have bought allot allot of corals from wwc on ebay always a great experience, but I also live in Florida, but the packages always fly to Tennessee then back to Florida, jet fuel is cheap i guess, I couldn't drive there and back for 40$
