A very discount marine supply store. Most of their business is online/phone/mail order, but they have a retail location at their warehouse in Waterford, CT. Their big spring sale usually has some unbelievable deals. The store is really quite low rent, but they have an amazing amount of stuff in stock, and their prices are often much better than the competition.Who or what is Defender? anything like the REI sales of yore when there was only one store in seattle?!?!?!
