I found the best price for a hard drive on Fry's web site. I placed an order. Three days letter my credit union called asking if I was in California. I replied no. They were calling to notify me that someone was using my MasterCard Check Card around the L. A. area at various merchants. I checked my checking account and the charges started the same day that Fry's "fulfilled" my order.
I notified Frys Risk Management department. They sounded concerned, took the information and said Customer Relations who call me that day. No call. The next day I called Risk Management again. They said they got a message that both my home and cell number were disconnected. She said she would have Consumer Relations call that day. Still no call.
I have a reasonable belief that someone at Fry's Order Fulfillment center is "skimming" credit card numbers. I recommend that no one buy on line from Fry's.
They cannot keep your credit card data secure.
