I have pondered this for years. 12-3 generally costs ~80% more than 12-2. Same ratio in 14ga.
Why this should be, I don't know. It would seem to me that the one cable consists of about 1/3rd more material than the other. It will weigh about 1/3rd more. Is the cost of shipping the stuff even remotely a fraction of the cost of getting onto the shelves?
Seems to me that vastly the most expensive component will be the copper, with the oil for the plastics coming in second, and by a fair bit. A 1/3rd increment in the cost of making the stuff should result in about a 1/3rd increment of the price to purchase?
Yet another good argument for working with flex conduit and individual conductors.
