Also, not all erroneous charges are fraud. Some years ago, while working in the corporate world, I bought most of my business clothes at Nordstrom. One day I had purchased a couple items there and, while they were being rung up, I spotted a jacket I hadn't noticed. I was trying it on and my salesperson came over to help me. I didn't buy the jacket, but when my bill arrived I couldn't make sense of the charges. Yes, I had purchased items X and Y, but what was this $160? I called Nordstrom. They could identify EXACTLY what was purchased just from the code on my bill. The $160 was for a pair of pants in a size 2. I was quite slender when I was young, but I NEVER wore a size 2 pants! I knew those weren't mine! I think what happened is that my salesperson laid down my card to come over and help me and another salesperson mistakenly picked it up and rang up another sale. An honest mistake, but not one I wish to pay for.
