So a few days ago the wife was reporting problems with her e-mail and one of those e-mails she was having problems with was groupon. So I decided to take a look at the e-mail headers to figure out when they were sent and I found this little gem.

It’s a cute trick to get people who understand headers to be interested in the company.
