Hi A.!
Congratulations on your upcoming vacation. I am sure that you will have a great time.
I concur with the other posters about the discounted tickets through Undercover Tourist and/or Mousesavers. I have good things about them - though I have never used either one of them. I definitely would only go through an approved vendor for Disney tickets - no ebay, etc.
If you are looking for ways to save money at disney, it depends on what you are looking to save on - food, souvenirs, etc. One of the best resources for anything disney is the website - www.allearsnet.com they do have a couple of tip sheets on ways to save money. Also, you can search for $$ saving tips that readers have posted.
Please let me know if you need any more specific ideas, etc. I am more than happy to help.
Have fun.
K.
