Omg! I had no idea the Costco Amex did that on restaurants! Bahhhh! I don't shop at Costco though.
If you shop at costco i really think cards worth it. 3% on gas, 2% on restaurants and travel. That alone will cover the membership fee.
I agree, the Costco membership fee is $50, and right now am only using the card for Gas/Costco Purchases and it'll cover the fees plus some. And the check they send out annually you can cash it out at a Costco or put it towards your statements.
