How do I get the 25% discount the email said I'd get if I file by 3/26?

Nevermind, I think the promotional email is not even for the product I'm using.  It says it's for TurboTax "Live" Deluxe.  I'm using regular TurboTax Deluxe.  I'm really aggravated that TurboTax sent me an email with a promotion that said come finish using a product other that what I'm using.  I wasted a lot of time trying to figure out what this promotion wasn't working.  Thanks for trying to help.
