Discover Card at 0%

Early this morning I awoke in a panic worried that I had not made two transactions on my 0% balance on my Discover card this billing cycle. UGH!!! Fortunately, I still have more than a week to make the transactions otherwise I will lose my 0% interest rate. The rate was the only reason I applied for the card. I have had it since late January 2007 and have saved a lot of money in interest with it. I have also earned a $20 rebate which I promptly put towards my balance. I have been able to pay off approximately 25% of my original balance in part to not having to pay any interest on the balance. I will need to stay on top of the two transactions per month stipulation though. I plan to pay this card off with my federal tax return early next year and that will be the end of my 17 plus years of continuing credit card debt. It is strange to think that ever since I got my first credit card 17 years ago I have always carried some type of revolving balance on my cards. I have never paid them all off completely. Something has always come up. Maybe I just never made it a priority.
