If you shop at the nation's largest arts and crafts chain, you should read this.

Three months ago Michaels' Arts and Crafts warned customers of a potential data breach. Thursday they confirmed that as many as three million debit and credit cards may be at risk.

Shoppers who have used a card at the point of purchase in a Michaels store between May 8th, 2013 and January 27, 2014 should watch their credit or debit card activity closely.

The hackers have customer names, card numbers, expiration dates and PIN numbers.

CEO, Chuck Rubin wants customers to know that the problem has been identified and contained and that it no longer poses a threat to shoppers. CLICK HERE for the post as it appears on the Michaels website.
