Last month I took out a Mint card and was offered a credit limit of £2500. I didn't ask for any balance transfers when I applied though am now making use of the 0% introductory offer for purchases and transfers. I would like a higher credit limit than this to do another balance transfer (at a transfer rate of 2.5%) but wasn't sure if they would allow this given I have only had the card a month.
Is it worth the risk asking for a new credit limit or should I try to take out another interest free credit card instead?
