DO NOT DO THIS. I WILL NOT BE HELD RESPONSIBLE. I've just realised that this is possible, after the ladbrokes thing... I paid onto my ladbrokes account from my credit card. Being a mastercard, it can not withdraw to the card, so withdrawals are straight to my bank account. So, the scheme is this. Get a mastercard dedicated to this purpose, as well as a high-interest current account as some financial institutions are offering (4.5% AER). At the beginning of each credit card billing month, transfer the entire balance possible to ladbrokes. Immediately withdraw this into the high-interest current account. When credit card bill appears, pay it with the same amount that is in the high interest account. Once paid, immediately repeat process. This allows you to accumulate interest in the current account without incurring any on the credit card. The interest you accumulate is not on money that's actually yours, but as most accounts have the interest calculated daily, there's a significant amount to be gained with this. Say the cc limit was £2000, you could earn £90 in the first year for spending 5 minutes per month doing the deals. Do this with several credit cards and you could start to bring in enough to pay for the christmas presents each year, or a flight somewhere nice. And imagine the airmiles....
