Millions of people who shopped at Target on or around Black Friday (Thanksgiving through December 6th) have probably had their Credit/Debit card info compromised. The Secret Service is investigating.

Apparently some 40,000,000 people may be affected.

You had to have physically shopped at a Target store to have this happen to you.

Please check tour credit/debit report everyday. The longer you let it go, the less likely any fraudulent charges will be forgiven.
