There is a great way! Read the DIS everyday!
Actually I have found the best way to keep up with the special offers to sign up for the daily Page Change information at the mouse savers website--umm, not sure if I am allowed to post the link, but Mary is a member here and we often talk about her site and post about needing the newsletter. . . I will post most of it, and if it is not okay, mods, please go easy on me
mousesavers.com (add the appropriate w's)
On the home page, scroll to the bottom where it says "Watch this page for updates". You have to "sign up " with an outside company, but I have been signed up for 2 years and never had any problems or spam because of it. Anytime Mary changes something on the home page it will show up in your email inbox. Most days it is just information about Disney Shopping deals (often good ones!) or things like that, but a few times a year

A GREAT DISNEY OFFER! Worth the 1 extra email a day the rest of the year!
