Last year at the Annapolis Boat Show...
I was shopping for a Raymarine E-80 multi-display. The "boatshow special" on this unit at the Defender booth was a free GPS antenna to go with it. The antenna was a $300 value so that's nothing to sneeze at. May get better deals on other brands.My experience is that you can get some sort of discount on many major items such as electronics, boats, props, custom mattresses. I even buy a zinc for my feathering prop each year at the show, at a discount. List $30, show price $25 and no shipping charge.
