When I was a student I got one of the accounts with a 0% overdraft and took the money out and put it all in an ISA and made money it. Very simple easy money, now I see adverts all the time from 0% for 12 months credit cards. Is it possible to do the same sort of thing with them? Max the credit limit pay 0% and stick it in an ISA then pay it all back at the end of the year?
