We have done a lot of DIY projects and a few contractor-bid jobs; we've purchased from Home Depot, from Lowes, from a local cabinet maker, from Canyon Creek, and from RTA, so it's fair to say that as a non-professional, we have a bit of experience upon which to base an opinion:
We wanted to redo our 1984 laundry room. It's a big space that also includes a bathroom. We weren't in a hurry so I did a lot of research and shopping. But we were getting $10k bids and I just did not want to put that kind of money into laundry room cabinets. When the last "economical" bid came in at $9k and was going to give me particle board boxes, and "we can't do custom depth drawer boxes," I decided to go with cabinets.com - who could give me all the bells and whistles of "high end" cabinets* AND customs sizes/depths, as well as the fun of spending hours (days?) playing with the options. Yes, I was super nervous about ordering a lot of cabinets from an on-line source, but we saved more than $3400, got more cabinets, and a sink base for "free".
We received our order in April and over the weekend, started the installation. I have to say, I am beyond pleased with the quality and look of the cabinet.com product. Everything came undamaged; the local delivery company was epic; and the cabinets themselves are solid, well built, and superior quality over any other cabinet we have purchased. Part of our order included 21"x84" pantry cabinets; they were perfectly plumb, include 5 shelves, all of which are adjustable, and well finished. I actually felt giddy putting our stuff back in them.
While we had absolutely no contact or follow up with customer service, I never got that with the local company either.
As a side, we ordered Willow Grey and Alabaster. The grey is warm, almost like BM Grey Owl, and the alabaster is a perfect warm "off white" - no yellow or taupe.
