This card is worth it just for the William Shatner logo. I get a lot of laughs whenever I use it. And with laughter being the best medicine, I save lots of money on medical bills. The 2% is icing on the cake, and I hope it stays for a very long time.
I use only 2 other cards -- Blue Cash Preferred for my groceries and anyplace else that only takes AMEX, and PenFed Cash Rewards for gasoline (this card stays in my glove compartment and comes in handy when I forget my wallet but am out driving without a license).
