Thanks to everyone who offered to sell me shells, including Amphidromus. Because I need large quantities (~200) and because the shells will essentially be wasted, I can't justify spending of the sum that would result from the prices offered to me (about $3/shell) from private funds (I am a self-supported researcher).
