The Starwood Preferred Guest Credit Card from American Express has added a bonus offer for those who apply for the card and spend $15,000 in their first six months — 15,000 Starpoints will be added to their account. These points are in addition to the usual sign-up bonus of 10,000 Starpoints with first purchase — enough points for up to three free nights at a category one or two hotel. Visit http://www.americanexpress.com/spg25 to apply for the card. The first year is fee-free, $30 thereafter.
