Until 2:15 am ET (or 100% claimed), Amazon offers Prime members the Instant Pot 9" Tempered Glass Lid for Electric Pressure Cookers, model no. IP-LID-22, for $11.95 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise, it adds $7.) That's the lowest total price we could find by $2, although we saw it for $2 less in May. It fits most 5- and 6-quart pressure cookers.
