my wife just got a card. if i stack a csr right on top of her card, meeting the both spends might be (depends on travel for work, which i have no control over) hard. if i wait until march it wouldn't be much of a problem.
if i can trust the the points guy, who seems to be the only one saying you can wait until march, and work up the resolve for an in branch application, waiting is easy. but even the points guy doesn't claim the march thing is guaranteed, just says "chase has suggested" the offer will be available in branch until march.
