I had the two pieces of rub-rail insert (I call them scupper) shipped from Amel for my hurricane repairs in Puerto Rico in Dec 2017. Price was $2,686 with shipping. They were about 5 feet too long for each side but better long than short. They came as Bill indicated, on a wooden pallet (sort of a miniature pallet) about 2 to 2.5 ft square wrapped in shrink wrap. They were heavy. So indeed, the shipping is the greater part of the cost. About $1,800. It was covered in my insurance settlement. I had been considering replacing mine when Irma/Maria intervened and gave me a bonus in that small way, (didn't make up for the lost year of sailing while repairs were made. The new scupper looks so nice I would consider pressing ahead despite the cost. When you install it you want to make sure that it is installed in compression because it does shrink a bit. It is easier to install when in tension but to better fill and assure it doesn't leave a gap insist on putting it in compression. I also left it a foot too long at the stern and at the 6 month mark I made a final trimming to avoid having a gap due to shrinkage.
All the best,
