Just visited Costco today to get a quote for new tires and when I mentioned that I was a day late learning about the .01 cent install offer that expired the counterman told me that Starting 10/3 that Costco would take an additional $60 off if you pay with the Costco Visa card. Also that the Michelin $70 off would be extended.
So today’s mail had the October Costco book and it confirms what he told me.
