i hear this Citi Card enables one to receive 75k points if you spend 1,500 within 3 months, then their is a Citi Amex card that also enable you to receive 75k within 6 months if you spend 4k, and then a Citi aa buisness card if you spend 1,500 within 6 months. Can someone please confirm the exact pattern and spending requirements for each of these cards, and after you apply do you call up and have them match it, bec there is no mention of any points on the applications? will the 3 browser method work for these??
