Got an e-mail today from Bank of America offering an “upgrade” of my current Platinum Visa card into a Visa Signature card. Same rates and fees but instead of a pre-set credit limit, the card would have a revolving limit. The highlight:

Your revolving line, which may also be referred to as a credit limit, will be disclosed to you when you receive your card and, generally, on each monthly statement. We may change your revolving line from time to time.

Seems like another ploy to reduce the total credit BofA is extending.
