For corals I shop at CultivatedReef.com. It is a smaller shop, but I believe in focusing on a select collection of corals. It is the key to success in long-term cultivation. I avoid wild and maricultured corals and choose the tried and proven "classics", as these have a pedigree in our reef tanks. CR has a good selection of beautiful, well known corals in the trade. They are careful to send healthy, chunky, colorful frags. If you wait for one of their super sales you will make out like a bandit! I typically save up and bundle a larger purchase amount so as to get free shipping. The bottom line is improved chances of success with corals at competitive prices. Plus great customer service -- I probably nag them too much, but they seem to take my questions politely and always give me good advice, and that's worth plenty, too!
