I've had mixed luck with them. The inverts usually end up with 25% of them either dead or almost dead. The fish and corals have arrived in decent shape though. I did order 1 coral that didn't make it to me alive, but all the others have. They do offer a live arival guarantee and a 15 day guarantee, so you are covered if anything dies. The only issue with the credit from them is that you must meet a minimum order amount before you can apply your credit (so in other words you hvae to spend X amount out of your pocket first!) and it can't be used on dry goods or shipping. But I think that is pretty standard with online livestock.
