Yes, they did spend a few minutes asking me about my "business", so you gotta be prepared. Lasted about 5 minutes, asking me what, when, how, how much, where, and why.
They had a 1-2 page form that they go through. It allows them to select the best business checking account for your needs... But I guess you can simply tell them you want the Business Classic checking account (per the offer).

I don't really have a business, I just sell stuff on the web now and then, so I based my business on that.

The question I have is: what do you tell them when you close the account (after receiving the 50,000 CO miles) and what do you tell them when you try to open the same two accounts a couple of months later for the new promotion?
