"I noticed AMEX had a 8% rebate on a purchase from Tirebuyer. I have been a customer of TireRack since 1985, but I decided to give Tirebuyer a shot on winter tires. Their online site was easy to use, found in-stock Pirellis (the only winters that were not out of stock), choose Spiffy as an installer, and paid. Received an email acknowledgement. It was two days before the install date with nothing from Tirebuyer or Spiffy. I started a chat session with Tirebuyer, after 15 minutes I was told that my order was canceled. The chat rep never answered my follow-up questions, so I decided to call them. It was an overseas rep, and she could not explain why the tires became out of stock when their site still had them in stock. Something about "not being responsible with inventory." Fine, never going to use them again... I did get call from Spiffy the next day, and had to tell them the situation. "Simone" needed to get with their stateside Tirebuyer rep and promised to give me a call back. No surprise, I never got that call back."
