Within the last couple of months that happened to me with Walmart. I never shop at Walmart, I'll go out of my way to avoid there in store or online, but I had my credit card on their website from the last time they failed me years ago. One night I saw a $450 charge on my credit card from Walmart and obviously knew it wasn't me. I called, disputed the charge and got the card cancelled. I couldn't figure out how someone would have gotten my card recently, so I went back and logged into my Walmart.com account and low and behold I saw the order for a Tablet and I eventually got the e-mails where it was being shipped to my address too. Someone must have hacked my account and just used the cc on file with Walmart.com to buy it off the site. Not sure what they were trying to pull, but it didn't work out for them.
