I don’t think the sale of shells at the seashore has ever been tightly regulated, and who knows what an unscrupulous shell salesperson might try to slip you (not trying to slander Sally, though, she’s an honest vendor.) I recommend being a careful buyer; why not check in one of our guides to seashells in O’Neill Library (QL400s, 3rd floor, row 80)?
