In answer to my question, I found this linkhttp://www201.americanexpress.com/business-credit-cards/business-card-details/american-express-gold-business-card/any thoughts?
I know that the 30K SPG offer is "officially" dead now, but it might still be alive at the Amex application call center. I would suggest you give them a call and try.Way better that 50K MR points.
I wouldn't say 30K SPG is way better than 50K AMEX.
