This popular offer is back, but only for a limited time. When you apply for an SPG American Express card by September 4, 2012, you’ll earn 30,000 bonus Starpoints–that’s 10,000 Starpoints after your first purchase and another 20,000 Starpoints after making at least $5,000 within your first 3 months of cardmembership.

It’s been about a year since the last time this offer was available, so if you’re interested in the card, you should act quickly.

Update 9/5/12: This offer has now expired.
Note: This offer is available for both the personal and business versions of the card.
