Great card for business. Allows me to track everything and great customer service.

I love this card! Having no limit is a great thing, although it makes it hard to rein in spending! But I really enjoy the benefits we get from this card. We accumulate points with each dollar we spend and have been able to use those points to get a lot of gift cards for different restaurants. The only real issue we have is having to pay the whole balance every month.

I've had the American Express Preferred Rewards Gold Card for several years and I love it.

One of the main things that I look for in a credit card is a good rewards system to earn points I can redeem for air travel. After a bad experience with a US Airways MasterCard (US Airways has very limited flights in certain parts of the country, which makes their points pretty, well... pointless), I was happy to find that the Preferred Rewards points earned with this card can be redeemed for tickets from twenty-some different airlines. So wherever you need to go, you're pretty much guaranteed you can use your reward points to get there.

American Express will give you 1 point per $1 spent, and there are no limits to the reward points you can rack up. There's no annual fee for the first year with this card, which is nice, but the reward points more than make up for the annual fee after the first year.

While the US Airways Dividend Miles World MasterCard I had before didn't charge an annual fee, it only gave me 1 mile for every $2 I spent. With the Preferred Rewards Gold Card from American Express, you get double the rewards points, and you can redeem them for all kinds of things in addition to air travel on many different airlines. I'll gladly pay the annual fee on this card in exchange for getting points I can actually use.
