These are not mass-produced, they are built by hand, so the $149 USD price tag seems more than generous.

The mail­boxes are hand­crafted out of marine grade stain­less steel for a clean mod­ern look, and tough to weather the ele­ments. Fea­tur­ing a real full-length piano-style hinge [no cheap rolled or folded steel hinges].

The seg­ments are welded together, and then the edges are hand-buffed.

Approx­i­mate dimen­sions are 15 7/8″ x 8″ x 4″.
