hello! im getting my optimus today (used; but hey-money is tight)... i wanted to know how kickback codes work? do i have to sign up for it on the website or can i just use someone's kickback code? (i searched the forum and only found people posting their codes but i dont know how to go about using one) if you give me the most informative answer i will use your kickback code! =] and when i sign up for it i will give you mine in return!
