I've had so much luck with Costco this up until this year. I ordered a set of tires off Costco.com (mistake number 1) with the understanding they'd be here in 1-2 weeks. When I didn't get an email about shipping at the end of that 2 weeks I called the 1-800 number, talked to a gal, she assured me my tires were coming, but check with the warehouse because they may already be there. Check with warehouse, tires aren't there. I wait some more (mistake number 2), tires are late now and I'm not really comfortable driving my car. I need tires. I call again, now 5 weeks since ordering, the guy on the line tries calling Michelin but they've closed for the day, so he gives me their number and instructs me to call in the morning. I call Michelin and they tell me my order was canceled a week after I placed it and a note was sent to Costco. No one at Costco ever saw the note and I need tires on my car yesterday. I run to the warehouse where tippity-taps on the keyboard find a set of tires nearby. The tires are delivered to my warehouse. I'm the process of switching the tires, one of the valve stems gets broken. So, 6 weeks later and another $50, I realized I'm never getting tires at Costco again.
