Credit card companies frequently are coming up with new ways to sucker customers. The beleaguered industry is certainly not without its benefits but the methods used by many companies are outright slimy. Consider the advertisement in the mail from Bank of America. The ad for Zero Balance tells how I can get an unsecured loan of "up to $50,000* at competitive non-variable rates."

There is not even one little footnote symbol next to the "non-variable rates" portion that is highlighted in yellow for would-be borrowers. What does a non-variable rate mean? Is it the fixed rate that many would commonly think it might be? Well, no. While there is no footnote indicator there is an explanation in the fine light gray print on the back it explains:

By "non-variable rates" we mean that the APR will not automatically vary with an index, such as the Prime Rate. We reserve the right to change your APR, fees, or other credit terms at our discretion.

So it turns out that "non-variable" means they aren't tied to a somewhat predictable index, the economy or any of the normal things that most outrageously priced credit cards are tied to. Instead Bank of America can decide, at their discretion, to increase your rate to the maximum the day after you sign up. In fact if you sign up with a 10% maximum APR the next day they can change it (changing the credit terms) to a low 33% APR. Read more about The non-fixed APR
