Got this in the mail today and I can't tell you whether it is targeted or not. The promo code on mine was: DSG1NF6. The enrollment link is:
www.WorldPerksVisa.com/Enroll
Miles are doubled for up to $13K in spending between now and the end of the year. From $13,001 - $21,000, the bonus drops to .25 mile per $1. From $21,001 - $26,500, the bonus is .50/$1 and $26,501 - $50,000, it's back up to one mile per $1. (No bonuses past $50K).
The enrollment link seemed a bit sluggish, but it worked after a few tries. (Must enroll by Aug. 31.)
