NY aquatics will check the eggs to make sure the eggs contains a cuttlefish before shipping it to you. Sometime Michael will add one or two extras if he know you are really interested. You should call the store and talk to him and make sure of the ship date to make sure you are home the day they arrive. Good luck.
I had 10 out of 12 eggs hatch from him but I kept them in a 10 gal tank to start. all looked good and 2 week later they all died in within 4 days. I called up a few experts from Newport Aquarium and they told me they had the same issue. They kept them in 6 different tanks, checked the water daily and they all died. They feel it is a food issue and we have been trying different types of food but from what I here from this site is that mysin shrimp are what to use. The confusing part is that the shrimp are as big as the baby cuttlefish and they aren't big enough to eat them till they are a few weeks old. Plus keeping them in a breeder net on the main tank is better than keeping them in a 10 gal to start with, less water problems like high nitrate levels.
I am trying again and have 5 left out of 7, just lost 2 the other day. But I am going to try to feed them mysin to see if they will eat them.
