If your credit card number had been stolen instead, you would receive an immediate credit from the card issuer and never have to worry about those charges again.
Dave Ramsey pointed out today that rich people didn't get rich with credit card points, and that credit doesn't build wealth. He wants you to cancel all of your credit card accounts, lest you be tempted to misuse them, and use a debit card instead.
I would like to point out that rich people got rich by making intelligent financial decisions–– and giving people the magic number to empty your bank account, causing you a bunch of grief in dealing with it, is not a wise financial decision. Neither is charging up a credit card full of crap you don't need.
Way to go on making yourself debt-free, now continue to make wise financial decisions, and you can stay debt free AND enjoy the protection afforded by using a credit card (fee and interest free!)
