im guessing if you bought it at target you probably live in the states
im in canada but this is what i do
amazon.ca has a deal where when you make a new account and pay with visa you get 10 bucks off. not sure if theres something similar for u.s. visa cards?
i think buy.com gives you 10$ off if you use google checkout
i buy some games used from people over the internet using sites like craigslist,etc. just meet them at a mall and make sure its in good condition. never had any problems
