75% of my nicest corals came from Pet City, and most of them were priced within 15% of what J&L would have had them priced at. Pet City is my favourite place to buy corals by far. In almost every order they get in there is one or two corals that are 'A' grade, and they aren't priced any higher than the others. Keep your eyes open and scoop up the good ones because the ones that aren't as nice as priced just the same!
I go to Total Pet if I want Nassarius snails as they used to be the only ones in town that carried them, but I think Interior Reef does now too.
I don't usually find that ReefKeepers has much for corals, but they tend to get nicely colored Euphyllias. Their coral prices are usually quite good.
Interior Reef gets lots of nice stuff for good prices as well. I haven't bought much livestock off him mainly due to my tank being full.
