Which binding is the least expensive – perfect, Wire-O, or plastic coil?
In run lengths up to 500, the differential in cost of these bindings is negligible. As run lengths increase, perfect binding becomes the least expensive option because the material costs of Wire-O and plastic coil are inherently higher. Of the three, plastic coil at higher run lengths is the most expensive, not only because of material costs, but because of the hand labor involved in installing it.
