Wire. When you buy a 250' roll of wire, the price per foot works out to be much less than if you buy a 100' roll. You pay even more per foot in a 50' roll.
Outlets/switches. A 10-pack of outlets is $3.57, but purchased individually, they are 59 cents each. Single-pole switches are $4.90 per box, but 69 cents individually.
But some things that do not offer a package discount:
Recessed lights. If I buy a box of 6 lights, it is the same price as buying 6 individual units.
Circuit breakers. A box of 10 circuit breakers is exactly the same as buying 10 individual ones.
Why do they have an inconsistent pricing scheme among electrical supplies?
