My family has used Harmon's for years. Sadly, we have all individually started going elsewhere. Customer service has changed, I never go in the garage even CLOSE to my scheduled appt. time even when I'm early, and I've had issues about them not looking very hard for tires I want. I've bought 20 or more tires from them, and the last several times I had to do research on my own to find the tires they told me "Don't exist". In one instance, I just turned around and studied one of the DISPLAY models they had there... it was the tire and size I wanted and the woman told me they didn't make them! She grumpily did another search and found out they were even in stock!
Another time, they told me they only had 2 options of tires for a VERY common truck tire size. I went down the road an they had 9 options for me with prices. I went back to Harmon's giving them the benifit of the doubt. I got the woman (same one from before) to do another search for a specific tire I wanted. She grumbled as she found it, and quoted me $200 more than the company down the road, and that was with the other companies "hazard protection" as well. Very disappointing.
