SPG 30k will be back either today or tuesday. 10,000 Starpoints after the first purchase, and an additional 20,000 Starpoints after spending $5,000 within six months. The increased sign-up bonus will be valid from August 7 through September 4, 2012. So, if you've been waiting, now is the time. If you want a referral email from me please PM with your email address because I also get 5k SPG for anyone that signs up under a referral email.
I'll need to contact amex to make sure my referral email will be for the new bonus. I'm going to send mrs. dave a referral for this and see if that flys. Then cancel my SPG amex that I've had for about 4 years and have her refer me back.
