I put everything on the credit card, to the tune of about $80,000 to $100,000 a year. I get back 2.5% to 5% back on every transaction so it makes me money.
My cards get compromised about every 6 months or so. No big deal, they always close the account, reverse the charges, and I move on.
My discover card actually got compromised today. A 5 minute phone call, and everything was taken care of. I don't raise my blood pressure or panic any longer. It's just not that big a deal.
