This is the cheapest price I've seen.

Can you tell the difference between Trochus and Astrea by looking at them. The problem with Astrea is if they tip over they can't get back up but you can get them on line pretty cheap so that even with shipping is about $2 per snail.
I think it's fairly easy to tell the difference between Astrea's and Trochus snails.
I just did a huge order through ReefCleaners. They don't have Trochus snails, but I've had really good luck with their Nerites, and you can't beat his prices on snails. Just a thought.
