Wasn't expecting a retention offer for the AMEX Platinum, but here goes:
20,000 MR points for spending $3000/ 3 months. I took the offer. (Had the card for 2 years, with little spend, mostly on any good offers, Saks benefit & $200 incidental benefit.)
Still have to fork over $550 for annual fee, but it offsets it a little, I guess.
