I just quickly thought I should add that I live in Australia.
My favourite DVD is Sesame Street and Sponge Bob. Now I know you guys are thinking she is too old to be watching that but I do like Elmo. So I will give you some advice to help make 3D movies and food cheaper.
1. If you have gone to a 3D movie once keep the 3D glasses so when you go next time you don't have to buy any and it's for free
2. If you have some Chocolate or chips at your house bring them so it doesn't cost anything
3. If you buy frozen coke at Mc Donalds I think it might be cheaper (this if you live near a Mc Donalds).
P.S. I know most people already do this but I think I will throw it in anyway.
