SPG (Starwood Preferred Guest) — For a limited time only, get 30,000 Starpoints® after making just $1,000 in eligible purchases during the first 3 months of Cardmembership. This is our richest offer yet for the Card. The offer will only be available June 30 – July 6, 2010.
Use the points for staying at a nice hotel or you can get a $150 Amazon.com gift card for 28,000 points.
I think the best use/value is for Hotel nights!
