Chase Sapphire Credit Card 50,000 Bonus

Update 7/9/2011: I have more details in my Chase Preferred Sapphire review.

This My Money Blog post has a good review of the Chase Preferred Sapphire Credit Card and the sign-up bonus of 50,000 bonus points after you spend $3,000 in purchases within the first 3 months.

This was also discussed on this FW thread.

It may be possible to double the bonus.

My Money Blog has a follow-up post which describes how you may be able to get a 100,000 point bonus ($1,000).
