There are a number of cone shaped snails out there. However any store that charges for MTS is ripping you off plain and simple. All of the new Sulawesi snails that were discovered a few years back are cone shaped as well so is Anentome helena. However the Sulawesi snails and Anentome helena are hard to come buy. Most LFS will not stock unusual snails. furthermore you need to look at your national and state import lists to see if they are available or otherwise allowed.
