Extremely clunky and difficult to navigate - I'm literally just trying to replace a tire I already previously ordered from you for same car, and when I filled out the form for make/model it kept trying to tell me I had to order a different size - form/algorithm is incorrect and too smart for it's own good - wouldn't allow me to select tire i wanted/needed and knew that I already had. Wasted 30 minutes for no reason. Very frustrating and nearly abandoned sale here as a result
