Friends of mine own a marine store here in Miami called El Capitan and have just recently opened up a website to purchase marine supplies that they sell at the store.
www.elcapitan.com
They have been opened since I can remember and the owner I have known for over 30 years. I don't think that they have all the inventory on the website yet but they do have an extensive catalog and they can most likely order just about anything you may need. I know that the pricing is better than West Marine or other big box stores and usually better that the others smaller ones also.

I know that we all are looking to save on all the things we are doing to our boats and would like the pricing to be good and have some service along with it.
Give them a look
