>>It's okay to use a credit card for everything, but you have to pay the balance each month. I use mine like that because I get air miles, which my wife and I use to take trips.You must be the master of the card, or the card will be the master of you, whether it's MasterCard, Visa, or otherwise!

>Naturally, I pay balance every month. Also, I get cash back (1% usually) on every purchase so I have stimulus to use it everywhere. At the same time, using it everywhere would increase probability of mistakes and/or fraud, because it is not possible, imho, to memorize 20-30 or more transactions made during previous month to verify monthly statement.

Think Pink Panther - theese ees nothing, I could easily remember 21-31 transactions! :}
