The Shell Man Inc., Marathon
If you are looking for any thing beachy, this is the place to come. They have several locations in the Keys, Key Largo MM 106, Tavernier MM 92 1/2 and Marathon Key MM 54. The prices are very fair and they have it all for the nautical buff. We picked up some really nice large shells at a good price. It fun just to walk and look around inside and outside.
