Damage and defective is a concern. You'd also have to check how the appliance is delivered. Delivery by freight might only be to the curb on a pallet although there may be an option to bring it inside at greater cost. You'd have to figure out how to get it inside which may mean hiring someone. Scheduling of freight delivery is sometimes a hassle. You'll usually have to quickly unpack and inspect for damage before the shipper leaves. I'm sure many people do it but saving 5-9% sales tax might not be worth the risk/hassle.

As previous poster said, make sure you check their policies. Many websites give you 48 hours to check for concealed damage and report it. Also many sites have substantial restock charges, and only deliver curbside.

Otherwise,build.com is part of the same comoany that ferguson is so my gut says it would be fulfilled by them at some level.

Have you shopped locally? Many local dealers can provide better service experience and nearly identical pricing.

Lowes will match prices AND give you 10% back on top of that, no shipping, so that should cover the taxes.

Do you know if Lowes does that price matching if you order from their website?

I think you have to go in and order it. They can order off their website for you. That was how I asked it when I asked them. I'd go in, show them what I wanted, and then show them the webpage that has the lower price of the exact same item.
