If you are a BT customer you can save money off your broadband and phone bill, but only if you have a BT credit card.

The card which is being issued by MBNA offers zero per cent on balance transfers for 12 months, zero per cent on purchases for the first three months, and a typical rate of 16.9 per cent APR thereafter.
The savings will be automatically taken off customers bill without them having to save vouchers or claim points, each card holder can save up to £75 a month.. For the first £250 of spend on the card each month, customers will earn one pence for every two pounds of purchases, over £250 and this rises to one penny per pound spent.
