OK, I went and looked. The prices are very good, but all the packages contain hermits, which I wouldn't want. I would just try to get as many trypes of snails as possible.
Reeftopia was willing to sub out parts of their packages for me to snails from hermits. I perfer a wide mix of snails as well with very little to no hermits. The hermits IME have picked more at living parts of the tank then cleaning up the dead or decaying stuff.
I've been dealing with Reeftopia for years and have always had superb results from them. We order pool from them for our reef club a couple times a year and get in $500 and $600 orders and everything has always gone very well. They have some great prices on some fish and other items (their royal grammas are awesome and only $6) if you are having problems getting to the free shipping break point. The best deals are when you can order in large quantities and split them up with some buddies.
