Costco is offering $70 off the purchase of any four Michelin tires along with $0.01 installation per tire using promo code MICHELIN17MAR this weekend 3/11 and 3/12 only.
You just have to purchase the tires and optional installation this weekend then wait for the tires to be delivered to your warehouse.
This is valid for any Costco member, not just Executive members. See the previous deal which expired 3/10 for possibly another $25 off:
