I just got a call from AMEX open about my new (a month or more) business gold card. He asked what my business is and what types of things I'm charging on the card and if I'm taking advantage of all the open AMEX benefits available. I acted friendly, and interested. But I was scared! I couldn't remember what I had used the card for! I told him I'm dabbling in ebay. "how long?" I said years, but only recently started thinking of it as a business. (I have no idea what I put on the application!) He told me about the bonus spending categories and their 100K/yr maximum and we laughed and he wished me the income to cover that much in bonus category spending.He seemed happy to note: I see you signed up under a very nice bonus (75K for 10K spending in 4 months), All very pleasant and helpful. Nice of AMEX, but my 'business' probably won't need much of their small business help.
