Defender has the Warehouse sale in March They also typically do sales during Newport
they also used to do one during Miami
not sure if they still do.
Hamilton Marine used to do a spring sale in March too.
If your buying
alot of stuff Defender used to have an outfitting service
where a special rep would put everything together with you I would ask I assume they still offer this.
As said you can also do price
matching or just see what some of the smaller guys out there will do as well.
Back in the day when I worked for a boatyard we had several wholesale accounts that required minimum orders to keep our discounts active, come November I would put together deals for discounted service
to keep guys busy during the winter and discounted parts
to keep our discounts. ( for example I once had to make a drive to pickup a pallet of batteries that we deeply discounted to keep our discount with a supplier. )
