One star is too generous. I placed an ordered on Wednesday, December 20th, and I paid for express shipping. I contacted Plumbers Stock customer support the next morning asking them to cancel the order since I found it at another supplier that could get it to me overnight. In response, "customer support" told me the part had already shipped, so I could not cancel the order. They also told me I would get a tracking number via an email notice for the shipment shortly. Based on their reassurance, I decided to wait for the part to arrive. As of today (December 26th) I still have not received the part, nor have I received the shipping confirmation I was promised. If the order had already shipped on Thursday as they said, I should have received it by Saturday or Sunday latest. Not only have I not received the part, but Plumber's Stock has failed to deliver it via express 2-day delivery, for which I paid extra. I am extremely disappointed and expect a full refund. Still have not heard anything from Plumbers Stock, in spite of numerous emails, text, and phone calls.
