The dispute protection is no joke. Once 10 years ago, I bought something from Kroger with a debit card. A few hours later, the merchant charged a whole bunch of random amounts to the card until the total climbed above $1000 and I blocked the card. It took the bank quite some time to get the money back. Thankfully I wasn't living on the edge and didn't have rent due around that time period or else that would have been a much more devastating event. Never have to worry about that nonsense with credit cards.
