What are the best tips for saving money as a university student?

I will be attending university this coming semester and am planning on maintaining a sustainable financial situation right now, but would like any good tips or suggestions to saving money as a student.


Question: Retrieving Javascript value from Page 1 to Page 2
Answer: I found out the answer thanks to some help of Chris,

I just added these javascript line :

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&amp;]" + name + "=([^&amp;#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}


Then I change my 

var email = $('#email').val();


to

var email = getParameterByName('email');
