Economy Supply Co at 632 East Haley Street, Santa Barbara, California.

I have used Economy Supply for my plumbing needs for many years now, starting with a major home renovation in 2004. The staff have all been unfailing helpful in all respects and a delight to deal with. They go out of their way to ensure that you get what you need and know how to install and use it. They carry a large inventory but if they don't have what you want in stock, they get it. Hats off to Ben, TJ, Tom and Brett.
Probably the best customer service of any retail business that I have experienced in 30 years in Santa Barbara.
