We have the same caps, and in the UK we have cards with 12+ months interest free. They do sometimes have small annual fees but nothing like the bank rate. My understanding is that it's a bit like bank accounts, it's paid for by people who don't pay their entire bill and take the high APR, leave a large balance after the intro period, etc. Basically, if you do it right, you win, if you do it wrong, you lose and often big.
