I pay for everything on credit cards for one reason.  Sure, it’s really convenient to pay for goods and services with credit cards, but I do it to get the rewards points.  I have a couple travel reward credit cards that I use constantly.  I have earned enough points to take a few really nice trips.  My wife and I fly to Las Vegas about once a month, using the points I’ve accumulated and we’ve also been to Paris.  I pay off the balance each month so I don’t have to pay a bunch of interest.  It makes perfect sense to use these cards for things you’d buy anyway.
