one credit card which i have never seen discussed here is the visa signature card from wells fargo. i spend an inordinate amount of time overseas and i consider it to be the best card in my wallet.

the card has no forex fee whatsoever on foreign purchases (not even the standard 1%). foreign purchases are simply converted into us dollars using the official exchange rate on the date the purchase is made. the card's customer service is top rate (almost as good as that which i get from citibank with my chairman card) and i earn double points on all travel and entertainment related charges (the bulk of my charges). if you choose to exchange the points you earn for cash (e.g. selecting their $600 cash reward for 50,000 points) you can end up making 2.4% cash back.

my card is from their private banking division but i believe all the wells fargo signature visa cards have similar terms and conditions.

if you charge a lot overseas, this card is well worth the effort and fee to obtain (wells fargo will waive the annual fee for you if you keep a high balance with them).

note: the only wells fargo credit card without the forex fees is their signature visa described in the above link. their other cards have a 3% forex fee.
