I get at least 4 of these a week. The current favorites are WAMU and Paypal. Before that, it was Citizen's Bank and CitiBank. If you ever get one that you think could be remotely credible, CALL the company. A friend of mine almost got ripped off because she got an e-mail supposedly from her cable company saying she had to re-register all her payment information. Thankfully she called up to complain and found out it was a phising scam.
