I don't know if many of you ordered 4 and tried to do the rebate for $80.00, but I did and I ran into a problem. I did end up calling customer service and after about 20 minutes and a supervisor they did credit my account the $80.00. It seemed to be a issue that Costco stock number didn't match the rebate offer. 4 tires mounted balanced and installed (2 to be mounted at a later date) for $400.00, a great deal anywhere, anyday.......Thanks to all for speading the info!
