My wife and I have been using CCs for the vast majority of our spending for years. We've had issues with CC fraud several times, but as Eric pointed out, you're not on the hook for that. The biggest issue with using CCs for daily expenditures is that it's SUPER easy to spend more then you should and buy crap you don't need...like antique Chinese bonsai pots...gotta be disciplined!
If you have any spare antique Chinese bonsai pots lying around and wish to get rid of the evidence, I can provide an address to the bunker for disposal.
