Went to Discount Tire to have one flat tire replaced due to a hole in the sidewall. When I showed the attendant the flat tire, I told him that all I wanted was a replacement for that tire. Without saying anything and ignoring me, he walks around the car to look at the other three tires and then proceeds to tell me I need to replace all of them. I told him that he was wasting time and again that I was only interested in replacing the one flat tire. Despite what I said, he wanted me to look at a poster inside the store to try help sell me on replacing all of the tires, which I refused. I was frankly taken back by the contempt the attendant had for me as a customer. I won't be buying anymore tires at Discount Tire anytime soon. On the tire that I did replace, at check out he added about 25% on to the price he verbally quoted earlier explaining that he added a replacement warranty and a tire disposal fee. Beware of the deceptive pricing tactics. Their sales tactics exude nothing but contempt for their own customers.
