Ken55 I think Thheath was referring to this perk regarding Costco Executive Membership
Executive Membership is our highest level of membership. Executive Members enjoy an annual 2% Reward on most Costco purchases, as well as additional values on member services, such as lower prices on check printing, payroll services and identity protection; an account bonus for money market and online investing accounts; free roadside assistance for vehicles covered through the auto insurance program; and extra travel benefits.
This is in addition to the AMEX card rewards in March??. I just got my reward check last month and was pleasantly surprised.
