The retailer said it was offering a 10 percent discount on Dec. 21 and 22 and free credit monitoring, calling the situation "confusing and disruptive" even as it tried to reassure potential credit card fraud victims — some of whom had said they were having trouble reaching the store.
The fury and frustration come as the nation's second-largest discounter acknowledged Thursday that data connected to about 40 million credit and debit card accounts was stolen as part of a breach that began over the Thanksgiving weekend.
The theft is the second-largest credit card breach in U.S. history, exceeded only by a scam that began in 2005 involving retailer TJX Cos. That incident affected at least 45.7 million card users.
Target disclosed the theft a day after reports that the company was investigating a breach. The retailer's data-security troubles and its ensuing public relations nightmare threaten to drive off holiday shoppers during the company's busiest time of year.
