[American Express] Amex Business Platinum .....50,000 bonus points!
Got a coded invite in the office mail the other day. Amex is offering 50,000 points after $5000 of spending in first 3 months.
I will scan the letter later for you, but for now you can use the RSVP code: 0091036670
It asks for the postal code of where the letter was sent, but you can input anything (I tested it).
