Brilliant e-commerce ideas begin in... Boca? Apparently so. Shore to Door Seafood (67 SW Tenth Ter., Boca Raton, 800-218-8147, Shore to Door Seafood), delivers fresh seafood anywhere via overnight FedEx packaging. Started by two long-time friends and fishermen, the company purchases its products directly from the local fishing fleet (especially its favorite 25 or so boats). On the Website, seafood lovers can browse the items by category, which range from sea bass to soft-shell crabs, or view the specials, which might yield something like five pounds of stone crabs for $109.95. (If you think that sounds pricey, compare to Joe's Stone Crab, which delivers only a few claws at a comparable cost.) Still better, you can send a friend an egift certificate ranging from $50 to $500. Even the pickiest of seafood eaters will love it -- especially when they discover that the site also features recipes.
