In my experience in pricing tires this past week every place I checked showed the same list prices including Tire Rack with free shipping There may be small differences in install costs or whether a rebate of some kind is offered.
I bought the CC2s from Mavis because I've gotten good service there in the past. Not this time at the Niagara Falls, NY store.
With a 1:00 PM Saturday appointment (not smart on my part) the car was eventually rolled into the parking lot around 3:30 PM. 10 or 15 minutes later I asked if it was still waiting for alignment. It turned out they forgot to do it. The manager then did it himself and I'm then ready to go around 4:00 PM. I asked for the alignment printout--no go because the printer is broken! At least I saw him working on it and I got a verbal report on one left front adjustment that was needed. The manager knocked knocked $25 off the $99 alignment for my trouble. At this point I'm in a hurry and didn't inspect the tires until I got home. Two of these directional tires were installed backward. Back to the shop just before 5:00 PM closing. All they needed to do was swat the right front with the left rear--that took 20 minutes. The next day I noticed they did not return my wheel lock socket. Back again--fortunately they had it at the front desk.
I get this was Saturday afternoon with labor shortages. But really....
