You save a bit by buying directly from the mfgr -
Brownell Boat Stands, which is what I did several years and three boats ago, when I had my boat hauled to my property each winter. They're located in Mattapoisett, Ma - about a 40 minute drive from my home.
Back then, I paid about 35. each for stands . . . but as expected, the prices have risen dramatically.
Brownell has nearly cornered the market - with retailers all over the world.
