New credit cards give all sorts of perks and incentives making swapping very attractive especially if you are planning an expensive purchase and want a long period of 0% interest.
to be honest I don't really know how they work. From your posts when the "money" in the credit card is paid off which should be soon, I just have to ask for more money.
I have realised that I don't need a NEW credit card - just new credit/loan. Is that right.
You have a credit limit. Say for instance mine is 5k....we can't spends over that. If we get the balance down to 1k...we still have 4k on the card we can use.
You don't need to apply for anything unless you wish to change providers. Your card had a credit limit, and provided you stay within that limit you can use the credit available until the expiry date.
