Notice the images below (click on them to enlarge them): The first one shows the email without the images, so you can read the tags, one of which says "Save 10% on flights."
But in the second one, when you load the images, no mention of 10% savings or how to get it. When you click on the email, it takes you to the JetBlue web site where, I guess, they hope you never saw the promise of saving 10%. But don't worry, you can always make a Pomegranate Martini!!!
Oh -and note the fun salutation to Mr. Soandso.
All I can say is that in a Barack Obama America, consumer abuse like this will not stand! There's a new sheriff in town, JetBlue demon-spawn!
