I Hate Credit Card Companies

I’m pissed.  I paid off my Macbook in three months to avoid paying interest on it.  I could have paid it all off right away, but I got 90 day free interest when I got it so I thought what the hell, might as well wait and get the free interest.  I figured 90 days equals 3 months.  I guess I was wrong.  My 90 days was up on the 2nd and I paid it off on the 12.  I guess 90 days is two months.  BASTARDS!  Now I owe another 40 bucks interest.  I guess I learned my lesson.  From now on 90 days interest free now means 60 day interest free to me.
