Costco Amex Card is a must for frequent Costco shoppers- get big cash back

This credit card can be applied for right at Costco. You get 3% cash back on gas purchases, 2% at restaurants & travel, and 1% on almost everything else including Costco purchases. I use the no fee card almost exclusively and generally get back about $450 for other purchases and about $100 for the Costco 1%. The two checks come about February and October.
