One thing I will never understand about credit card companies is why our credit limits are so high. Credit Card #2 just kept raising and raising my limit when I was near my limit (which was often). It started off in 1995 at $500. Then they kept raising it and before I knew it - my credit limit was more than I made in a year.
Out of curiosity, back in March(when I was close to the credit limit) I checked to see if I could get an instant credit line increase with Credit Card #2. They offered to give me $1,500 more, which I declined. Just the other day (since paying off such a large amount) I tried again and they wouldn't give me an instant increase.
What that confirms with me is that some credit card companies are sneaky. They see you are spending and give you more. They see that you are paying it off and they won't give you any more.
Interesting, to say the least.
