I recieved a warning in my e-mail from our security department this morning.
If you happen to receive an e-mail from Best Buy concerning an order that was placed using your credit card information DO NOT respond to it as it did not come from Best BUY.
This e-mail links to a site that asks for personal information and credit card numbers. Again do not give out any information.
If you have already respond to this e-mail contact your Bank or Credit Card companies immediately to notify them.
I have been unable to find more info about this but their customer care agents will confirm this. Call them at 1-888-BESTBUY if you have any questions.
I have not seen a warning on their website nor in their main greeting when you call their number.
