I just bought a nice 4x DVD burner and another monitor to go dual monitor from TigerDirect. I've bought a ton of stuff from them in the past without a problem. Credit card number and the secret pin number on the back.

Then a pop-up with multiple answer questions.

Which of the following five counties have you lived in - out of the five I've lived in three.

When did you purchase your home at this address xxx - month and year given.

Which of the following people do you know - my wife's maiden name was on the list.

What city is the following address in - xxx - the address of my home address from 20 years ago was there.

Who is providing this detailed data? I'm tempted to go back and buy a bunch of other stuff to see if it happens again.
