Through June 30, 2014, the Starwood Preferred Guest Credit Card from American Express is offering up to 30,000 Starpoints as a signup bonus. You’ll earn 10,000 Starpoints after your first purchase and an additional 20,000 Starpoints after you make $5,000 in purchases within your first 6 months of cardmembership. That’s an extra 5,000 bonus Starpoints, compared to what is normally offered for the card.

30,000 Starpoints is enough, for example, to enjoy 3 free nights at a Category 4 hotel or 7 free nights at a Category 2 hotel.

This promotion is only offered once per year, so if you’ve been waiting to get a Starwood Amex, now is the time.

The SPG Amex carries an annual fee of $65, which is waived for the first year. For a full review of the card, see this page.

Update 7/1/14: This offer has expired.
