Credit cards are a great convenience and money saver for me. I don’t have a card that I didn’t get at least $100 to take and they all give me a minimum or 1% or more. I pay the bill every month so I incur no interest or service charges. And I don’t have to go to the bank or ATM to get cash more often than 4-6 weeks.
My wife and I each got a Marriott Rewards card that gave us 2 nights in a Paris hotel in sight of the Arc de Triomphe that went for $700 to $900 per night, one night in Dublin and 2 Nights in Green Bay.
I also pay nothing for my bank accounts and pay no credit card fees.
No one should ever order anything with anything but a credit card. If the merchant or say, furniture store goes out of business, your debit card, check or cash is GONE. Your credit card will return your money if you don’t get the merchandise.
Most of my credit cards double the warranty on anything you buy with up to a one year warranty and many give you free rental car insurance. Also, some have no foreign transaction fees.
