Capital One Classic Extra card is offering 0.5% cashback on all purchases with unlimited cashback. We have saved up for wedding/honeymoon so my partner and I applied for a card each, paid a bit off on each card and then used our savings to pay the full balance off when the bill came through. This meant no debt, no interest but 0.5% cashback on the wedding and honeymoon costs. Admittedly the rate is fairly low but as we're getting it for nothing it's not bad if you're making big purchases. Also, the cashback on this one is paid out in January, great when you're skint after Christmas and for Jan sale shopping. It's also meant to be for those with low/no credit rating. I won't take out a credit card unless it offers cashback and some of them you have to spend a ridiculous amount of pay an annual fee so I thought this was a good deal really.
