There was a good point that the equivalent cash back on the Barclaycard is 0.029% or something - you can get up to 3% on other cards *and* pay less than 17% APR. My Cahoot card was the cheapest at 10.9% but although it's gone up to 12% - they are offering 7% to new customers at the moment, fsck knows why! Cashback is 0.5% which is not that good.
