Mavis Discount Tire

I brought my car in for brakes and an oil change. They called to let me know I needed more tires and proceeded to give me a quote for about $150 / tire for a Chevy Cruze. The name of the place is DISCOUNT tire and they're attempting to charge me for the highest price tire for a Cruze? Only after I declined his ridiculous quote did he tell me there were other options. I'm not here for you to rip off. Even worse, this is located in an area with a lot of senior citizens, which means there are plenty of people for them to take advantage of and rip off. After declining that ridiculous offer, he quoted $393 for my car. I honestly still felt that was high, but thought the work that needed to be done was pressing enough that it warranted a little extra cost. When I went to pick up the car, they told me it was $479. When I inquired as to why it was $80 over my quote, I was informed my quote didn't include my oil change or tax. Since when isn't the quote all inclusive? The work I needed done was an oil change and brakes, why not give me that quote? They're absolutely deplorable with their business practices and I'm disgusted by the amount of money they ripped me off for. I never had a problem with STS in the 20 years I've been driving, so I trusted whoever took them over. They are thieves and anyone who works there pushing their rip off agenda should be ashamed of themselves.
