credit cards
I would definitely consider transferring your CC balances onto a CC card which charges 0% interest on balance transfers, if you can find one.
I came back from a year's travelling this time last year with no money and got a CC with 0% interest on new purchases for 6 months. It saved my ass I can tell you - and by the end of 6 months I had gotten it together and was able to pay off the balance. But I was very careful with money.
I don't mean to criticise but I don't understand how people who are obviously in responsible jobs and earning these really good salaries don't seem to be able to manage their own credit card. Do they just ignore it?
