That American Express one looks nice, though reading about the points feels like a shell game. I think I could use it simply enough just for gas and groceries. The site was really trying to push me towards one of the $95/yr upgrades though.
If you spend roughly $3000 annually on groceries and gas the preferred ($95/yr) card is good. If you're interested in grocery and gas rewards then you may like the Pen Fed Platinum Rewards Visa Signature more.
