Starwood is offering 30,000 points for new cardmembers until July 6, 2010. This is one of the best offers for the Starwood American Express card for signup. Upon approval, $1,000 in eligible purchases need to be made in order to get the 30,000 points credited. If you have been considering this card, now is the time. They usually have the 10,000 point promo, so this is a much better deal.
On FlyerTalk, there was an excellent post with a comprehensive listing of good credit card promotions for travel/airline miles. American Express HHonors and American Express SPG seems to have the best deal at the moment.
