ok so i wanted to get my first american express card and I'm pretty sure I would get approved because I've received pre-approval letters for green, gold, and blue amex cards in the past and I was just wondering if its absolutely necessary to get an amex business card instead of amex personal for advertising costs? The thing is, I don't have all the formalities of a business...I'm just doing a sole prop under my own name so would it be awkward if I got an amex card and used it solely for IM?
