They are selling Michelin PSS (same spec, 225/45/17) for $668. Right now, they have a rebate ($70 Mastercard prepaid card) so that comes to $598. With tax + shipping, it comes out to under $700. Installation at a recommended shop is around $70 with all fees (disposal, TPMS, etc.) - had it done yesterday on my other car at Firestone. So, same price as OP, but for those without a Costco membership or aren't near a Costco since TireRack ships and have installers everywhere.
