I got my last crew from reefs2go, they had pretty good prices and everything arrived just fine. The snails that I order from them a few months back just spawned, now I have hundreds of little snails all over the glass.
I would order everything seperately then buying one of their "packages". On many of the packages the pricing is way higher depending on what you choose to get. For example you can choose 60 blue leg crabs or 15 red leg crabs, the blue leg would cost 30 bucks or the reds would cost 9 bucks, thats a HUGE difference. Just decide what you want to get and see which way is cheaper. They also have sales all the time, buy one get one free. The blue legs are on sale now, so you could get those cheaper if you bought them seperately, as Im sure they wont give you twice as many if you bought the package with blue legs.
