Hola, welcome to Costa Rica! Here, you can buy hermit crabs for 24,000 colónes, which is about 45 USD. This may seem steep for a hermit crab, considering you can get one for free in New Jersey. But if you are willing to spend $400 on airfare to sit on the beach (which you can do in New Jersey), surely you won’t be so cheap as to pass up a very nice hermit crab.
