I have been an R.C. Willey customer for years, always at the Summerlin store. On occasion I have had issues with their customer service department, but never anything major.
For electronics and appliances I highly recommend Jonathan Sutherland. No pressure, knowledgable and treats you right. I tell him what I need and he always nails it. For furniture I have had a couple of good experiences with Kaleen(spelling?) Friendly and knowledgable as well.
I have always been pleased with deliveries. I was surprised to read so many negatives about that.
Anyways......great business in my opinion and I will always return!
