See privacy policy.If you need to bump up your account balance to reach a reward, Starwood is running a 20% bonus on purchased miles until December 31,2010. 1,000 points is normally $35, but with this promo it costs $28. Hardly a bargain, but if you need some more points to reach a reward, this may make sense. Remember Starwood has a 20,000 max on purchased points per year.Link.[card card-name=‘Citi ThankYou® Preferred Card – Bonus Point Offer’ card-id=‘22145660’ type=‘javascript’ bullet-id=‘1’]
