I recall build.com gives a contractor a discount based on volume, size, etc. I dont know what this would be. In our contract we specified that surface fixtures were provided by the owner for installation by the builder.

These are Kichler’s same part number. So every component should be the same. The Amazon seller is Kichler.

Oops! Amazon is the seller. When I did my kitchen reno and for my current 4 bath reno, I am buying all these fixtures, sinks, facets and decor. I had the time and online expertise to search out savings. I probably saved over $1,000 doing this for kitchen.

"A cheaper option on amazon"

Define "cheaper". Will amazon come out and fix it if something goes wrong?

I doubt Build.com will show up or anyone else for a light that costs less than $150.

As far as I know, a Kichler light purchased from an authorized dealer (and Amazon is an authorized seller of Kichler products, per the Kichler website) are identical to Kichler lights purchased from a different authorized dealer, no matter who purchases them.

We are in the process of redoing the landscaping in our backyard, and it involved putting in a low wall with three post lights. Our licensed landscape contractor proposed a post light that can be purchased at Lowe's for $50 each. The light I wanted (and what we ended up purchasing) is the Salisbury post light by Kichler ($315 each, plus the pedestal mounts at $59 each, for a total of $374 for each light). I ended up buying them from 1 Stop Lighting (an authorized dealer). With the discounts that the site offered, I ended up paying $609.40 (plus tax) for all three lights and all three mounts, which works out to $203.13 each.

The lights were shipped to us directly from Kichler.

The builder more than likely will not give you full dollar credit for the light if any credit at all besides pennies on the dollar.
