I got this email from a former client (haven't seen her in a couple years):

"I've been trying to purchase a $300 Amazon E-Gift card by email in denominations of $100, but it says they are having issues charging my card. I contacted my bank and they told me it would take a couple of days to get it sorted. I intend to buy it for a friend of mine whose birthday is today. Can you purchase it from your end for me? I'll refund it to you once my bank sorts the issue out. Let me know so I can send you her email."

We tracked down her phone number and called.  Slow day around the office, you know.  She said she had been hearing from people she hadn't seen in years.  She said she had changed her email password.  I'm not sure that will help -- the email came from the same name, but a different domain.
