The other day when I talked to a Bank of America CSR, they told me that I could deposit cash into my checking account from my Bank of America Platinum Plus credit card. This card is newly opened, and should have 0% APR and 0% BT through February 2008 (I'm going to verify this to make sure of the terms when I get the card itself, any day now).

My question is...how does the bank make money on this? If there is a 0% APR and BT promotional...I haven't read anything about charging cash onto my credit card, and depositing the cash amount into my checking account. So, how does this work? Even with the 0% APR, are they going to do something like try to clip me with a cash advance fee of some type? I know they make money off from this somehow, since they aren't getting interest right now. Has anyone ever done this, and was there any kind of additional 'fee' for it?

no way will they loan you cash for free. that is unheard of in the credit card industry. read the cash advance section in your service agreement book

You better check your fine print. I have NEVER heard of cash advances being 0%. They are more like 22%

It is normally 0% on balance transfers and/or new purchases up until a particular date.

Wait for the card and read the agreement carefully (read the symbols and the fine print). Most cards will have a hidden fee somewhere, I would have a problem with the BT (Balance Transfer). In order for that to apply, you usually have to transfer money from another card or loan for that. To deposit their money, is usually a cash advance and other fees apply there, including a 3% fee on the amount.
Also read about missing a payment or being late only once. Most credit card company's will then charge you outrageous interest rates if on occasion your late or miss a payment.
