Was just searching for a credit card with a long interest free period to pay off my debt and found this one has 16 months! This means that you can move your balance over from another card and pay no interest on it until the period is up.
There is a 2.98% balance transfer fee, but this charge seems to apply to any card nowadays. I don't recommend you get this card if you want to use it to pay for things, as it doesn't have a great 0% purchases period - I will be setting up monthly payments then cutting mine up!
Looked around everywhere and this seems to beat all other interest free balance transfer periods.
