Share my passion for low interest credit cards
If you want to change your due date or move to a better rewards program, you do not even need to threaten to leave. Just ask politely. Even if you originally got your card under terms designed for credit cards for bad credit, you can improve the terms substantially, perhaps even to the level enjoyed by premium credit cards. You are most likely to get drastic improvements if you have had your card for at least two or three years (four or more years is ideal), have paid on time for the last year or two, and are using a small percentage of your available credit. However, even if you have had your credit card for only a year, are using much of your credit line, or have made a late payment or two, you may still be able to talk the company into giving you some improvements.
