Home Depot Credit Card Breach! Bigger Than Target? [UPDATE]

My credit card info was hacked. I get texts when my card is used. I received a text about three weeks ago that my card was used about 25 miles from where we were at a home depot. About 150 miles from our home address. It said I charged $200, then $1 three times. I called the company and got a new card in a week. Still unsure how they got my number, but I did charge something on line at home depot last spring. It wasn't a home depot card. My wife and I each carry a different card just in case this happens.
