Whilst on subject, I think its appauling that if it is true that your credit score goes down if you cancel a card. This should be scrapped. There are many people out there that are trying to reduce their debt, once done, cancel. A service you no longer require. Some people may have multiple cards and want to reduce them down, will they get stung because they cancelled?
I think it goes up actually! That's what I've always been told
