I have some credit card debt that is currently on cards where there is 0% interest for periods of between 14-22 months. There was a transfer fee of around 2.9-3.5% for the balance from old cards.
I originally intended to pay off these debts at the end of the 0% periods with the money I'm earning and saving. However, given that interest isn't being applied and the transfer fees are close to the rate of inflation in the UK, I'm wondering if I should just transfer my balances to another 0% card at the end of the offer periods and use my savings for something else?
What are the advantages and disadvantages to me in doing this?
