If you've ever been to Sanibel Island, you'd see this in action. Sanibel is known for its seashells, and the beach is covered in brightly colored, large shells. People are walking along the beach collecting them. Everyone gets into a seashell collecting state of mind. As a result, there are tons of shops selling seashells, too, and people are buying them. The ones you can get on the beach are nice but the shops have the nicest ones, like giant conch shells, etc.
