Typically credit card companies work off of an average credit score for their entire portfolio. Theirfore they offer teaser and low rates to strong credit candidates which produce little profit or potentially a loss on this upper tier but what it allows them to do is offer middle and lower tier people offers that will be far more profitable.
With respect to the rates they are derived off of some financial index. If the index goes down your rate will go down. If you are paying your bill in full each month it should not matter.
What I am seeing in the Credit card market is that they are reducing their benefit option. A year ago you could transfer account with good credit and their wer no tranfer fees. Now, most card companies are charging 3%. Better offers are 0 percent for a year and max transfer fee of 50 or 75$.
For those who are looking for a credit card they best deal that I have rfound for purchases is American Express Blue. O% on PURCHASES for 15 months. No brainer to put all purchases on this credit card and stick you money in an interest bearing account. At the 14 month mark you pay the balance in full and pocket the interest earned on the account.
