So i did just call in about the MR bonus for 'new' cards, specifically the 100k for 1k spend on a plat (or whatever the spend was). And the rep quoted me back the 1k credit for a new car with a 5k spend per year, telling me that because this is a merc card, its different then the plat and therefor not eligible for the MR bonus offers. I am not sure i believe that, will try again later this evening or tweet the question tomorrow when the twitter people get in to work.
