You won't believe this. I hardly believed it myself. So I decided to order something from Amazon and it has been well over 10 years since my last order. After changing my password I went to update my shipping address because I have moved 4 times since that last order. Amazon autofilled my current shipping address. Then I went to update my Credit Card information because it has probably been about 4 cards ago. Amazon autofilled my new CC information. And they knew my wife's cellphone number. My work doesn't even have my wife's cellphone number. WOW just WOW. I guess someone has trusted Amazon with all your credit card information living information and phone numbers.
Are you onto something or just on something?
