The grief is not worth the savings. After paying $1,100.00 for a new set of tires they scheduled me for the 1st available appointment which was a week later. I was the 1st costumer and early the day of my appointment but still waited 2 hours, I was ok with that. The next day I went into the garage to find my back tire flat. I was able to get enough air in the tire to return to Cosco, however I was told by a very rude employee I would have to wait 2 hours to get in. Frustrated I took my car to a reputable. Tire repair shop and paid to have a valve stem that was not installed properly. THANKS COSCO!
